Sunseeker 28 Metre review: First look at the luxury yacht – from the archive

The pattern of Sunseeker’s new model evolution reminds me of an Olympic long jumper – a series of short steps followed by the occasional giant leap. From the moment I clap eyes on the new Sunseeker 28 Metre taking shape at the company’s factory in Poole, it is clear that this is one of those big leaps.

Due to be unveiled at January’s 2013 London Boat Show, it marks a step change in the look and feel of Sunseeker’s larger craft that will soon be filtering up and down the range.

The fact that it sits squarely at the junction between the top of Sunseeker’s current Yacht range and the bottom of its Metre class of superyachts is no coincidence. It was precisely this desire to bring superyacht features within the reach of existing Yacht owners that kick-started the creative process.

Chris Warde from Sunseeker superyacht sales says: “Feedback from 88 Yacht customers was clear – they not only wanted big-boat features like folding balconies, deep bulwarks and foredeck seating but a more imposing appearance too.”

That task fell to Sunseeker’s design director, Ewen Foster, whose brief was to create an entirely new look that combined the volume and substance of the Yacht range with the dynamism and appeal of the Predator range.

Innovative designs for the Sunseeker 28 Metre

The shiny black forward section of the superstructure moulding is also inspired by its functionality, namely the desire to reduce the overall build weight and centre of gravity by using modern lightweight materials such as carbon fibre. “We pride ourselves on pushing the boundaries of technology without jeopardising the quality or reliability of our craft,” confirms Warde.

Hall of fame: The top 10 greatest Sunseeker yachts of all time

Sunseeker confirms manhattan 65 to debut at southampton.

The British manufacturer will be bringing a wide range of Sunseeker boats to the show, including the world debut of

Although carbon fibre is used to mould the flybridge hardtop, much of the deckhead and many of the structural elements, the pilothouse coachroof is in fact a conventional GRP moulding that has been covered in a glossy black 3M vinyl with the chequered appearance of woven carbon fibre. It may be an optical illusion but it works, reducing the visual bulk of the superstructure and imbuing it with a more sophisticated technical appearance.

However, the most spectacular of the three major design innovations on the Sunseeker 28 Metre, and the one that is likely to draw admiring glances from customers and rival designers alike, is the bold sweep of glass that encircles the aft end of the saloon.

The trend for ever larger saloon windows is nothing new but this is the first time we’ve seen an unbroken run of vertical windows, stretching from amidships to amidships around the stern without a mullion or pillar to interrupt the exterior styling. The effect from inside the saloon is even more startling. Despite its unfinished state at the time of our visit, the open plan living area felt more like a penthouse in one of those ultra-modern glazed apartment blocks than the saloon of a planing sportsyacht.

Low furniture ensures an uninterrupted view through the windows. Diners enjoy the added benefit of a folding balcony

Gone are the slashes of glass and GRP that have dominated the looks of almost every large flybridge yacht for the last 20 years, to be replaced with huge 2m x 1.1m rectangular panes of flat reinforced glass butted up against each other. Even the normal structural aft mullions, which yards typically use to support the flybridge above, as well as hide everything from air conditioning vents to cabling, have been replaced with curved sections of glass. As a result you can now enjoy an unbroken 270º view of your surroundings.

“Early on, we were attracted by the idea of creating a panoramic saloon,” says Foster. “On Med boats the saloon hardly gets used because guests prefer to be outside, so we wanted to add as much glass as possible to make it a more usable indoor-outdoor space.

“It was a challenge to have so much glass and still maintain sufficient strength in the structure. It also meant we’d need to give it a very different look so we decided to make the glass a key feature of the design with an unashamedly upright look.”

They achieved the necessary structural integrity by using a superstiff cockpit door frame that can withstand over 6 tonnes of compression and two deep but slender girders each side of it, which support the flybridge structure but barely interrupt the sightlines from the saloon.

To make the most of this goldfish bowl effect the sideboard to starboard (complete with 55in pop-up television) and the two big sofas to port have been designed to sit just below the window line.

The freestanding dining table takes pride of place further forward so that it enjoys the full width of the opening side door and folding bulwark section. It’s not hard to imagine settling in here for the evening, looking out over the folded balcony as a thyme-scented Mediterranean breeze wafts down from the hillsides surrounding the bay.

The galley opposite can be hidden from view with a roller shutter or left open for guests to admire the chef at work. Of course if you prefer your meals truly alfresco there is still a choice of no less than three outside dining tables to pick from: the large U-shaped dinette in the cockpit, an even larger one up on the flybridge or the more private setting on the foredeck.

Sunseeker 28 Metre – Below decks

Down below the layout follows a similar pattern to the 88 Yacht but the extra volume of the 28 Metre’s hull and the multitude of oversized portholes (all of the four cabins have at least one) create an even more inviting experience. The master suite and the two guest cabins are accessed via a gently curving staircase in the saloon. Unlike the 88 Yacht, this doesn’t intrude into the master suite’s deckhead, so the bed now faces forward with a walk-in wardrobe to port and a lavish ensuite bathroom to starboard.

The VIP suite in the bows is almost a match for the master. The tapering beam means there isn’t quite as much floor space around the bed, and the walk-in wardrobe and ensuite bathroom aren’t quite so big, but the added privacy of a separate stairwell leading down from the bridge is a luxury that even the master suite can’t compete with.

Owner’s suite boasts a walk-in wardrobe and huge picture windows

Gratifyingly, the crew accommodation in the stern also receives a significant boost. The large transom window lets natural light flood into the mess area where crew can relax, cook, watch television or access the engineroom without disturbing the guests. A pair of twin bunk cabins either side with a bathroom and proper walk-in shower completes this surprisingly comfortable self-contained living space.

It does of course mean there is no covered tender garage but a large hydraulic bathing platform and a crane on the flybridge ensure there is still plenty of space to carry a mini-RIB and a PWC on board.

To complement the new exterior styling, the interior also breaks new ground with a move away from rectilinear furniture towards softer curves, colours and fabrics. There are 230 different fabrics to choose from, 28 leathers, ten lacquers, eight granites and marbles and three woods (oak, walnut and cherry), which can be finished in anything from 40-100% gloss varnish.

Slender aft mullions barely intrude on the 270° views.

The choice could prove bewildering so Sunseeker have also come up with a series of 14 mood boards to show how the various colours mix and match. With names like Kiwi & Caviar and Truffle & Cointreau it sounds more like the menu in a new-wave bistro than custom yacht interiors but they should prevent any ill-advised colour combinations.

If this all sounds a bit too soft and cuddly for such a big boy’s toy, you’ll be relieved to hear that it’s very much business as usual in the engineroom. A pair of 1,925hp CAT C32s or 2,000hp MTU 12Vs on tunnel-mounted shafts give an estimated top speed of 29 knots.

Foster admits that the brief for the 28 Metre’s hull was to maximise cruising comfort and efficiency in the 20-25 knot range rather than all-out speed but assures us that it will retain Sunseeker’s usual handling characteristics. We certainly hope so. We’re all for embracing change when it comes to the 28 Metre’s looks but some things are better left untouched.

Builder and provenance - supersonic mkii.

Hi all, new member. Last owned/restored skiff before kids. Now looking at resuming my sailing. I need a boat that can be sailed single handed. It would be optimal if I could have 6 on board for drinks ;) Currently looking at tophat 25s, Endeavour 26s, Cavalier, Holland, etc I have my eye on a currently advertised Supersonic 27 mkii. Diesel inboard, fractional sloop rigged, 5-6 berth. Scott Kaufman designed but I cannot find anything further. Resembles the Choate built 27. Anyone have any smart leads? Also, any comments on suitability for coastal cruising? Thanks in advance. T

SuperSonics build by Doug scrivener from about 1975 onwards not sure about a mark two generally masthead rig one was made to rate 1/4 ton by shaving the stern called liberator phil y will be along shortly scott Kaufman still around but in the usa bit or age now but solid all rounder of their day

If you have the money you can certainly singlehand bigger than those boats - if you want the kids to stay overnight. Not to say you won't have fun on the Supersonic but as an ex racer, the Young 88 is my pick for gun monos around the 30ft mark and would be nice to singlehand. If we had a mono it would be a Dragon or a Young 88, or a Masrm 720 or ........

The Supersonic 27's where actually built as quarter tonners, they were the longest of the quarter tonners in Australia. I have a friend that crewed on one to Lord Howe Island when he was young and silly. The yacht handled it OK but the crew got a bit of a hiding and it was the end of my friends sailing career! There was a flush decked version I think was based at Batemans Bay that was sailed solo by a bloke that visited here once.

NSW, 3268 posts

They were designed as Quarter Tonners, but didn't rate low enough. As Lydia says, Brian Scrivener then did a mould that tortured the stern more about the AGS and modified his Librian to rate QT. Dunno how many others had the stern modified. At almost the same time as the SS27 was launched, Scotty Kaufman launched Okka which was Australia's first lightweight fractional quarter tonner. Okka and the Farr 727 pretty much killed the QT as a popular class in Oz. I think the "Mk 2" related to the change from a squared-off coachroof to one with rounded deck edges and a long slope down to the foredeck. The SS is a solid boat, like Hollands, Tasman 26s, Cav 26s etc. Probably more room than Hollands and Cav 26s; the only Cav 26 I've been on felt a bit claustrophobic down below due to the short coachroof. The Holland has a similar coachroof but more volume in the hull and seems to have a more open layout. All that style of QTs were pretty much designed for bashing around the ocean every weekend. My old boat was a little big longer and a reasonable amount quicker (28' but half ton speed rather than quarter ton speed) and had no issues rattling up and down from Port Stephens to Batemans Bay. My main issue with those QTs is that they were designed to rely on having a big Number 1 headsail to get going in light and moderate winds. You may either have to put up with less than brilliant light air performance under a #3, deal with sail changes and tacking a big genny, or perhaps put a few $k into a nice modern short-overlap all-purpose headsail that would be better than using whatever #3 the boat currently has. The Choate 27 isn't really comparable. Although it's a Kaufman of similar LOA, it's far lighter and not an IOR boat. The Choate rates 150 in US PHRF, which is a lot faster than a J/24 and would be quicker than an S80. In contrast, as an early '70s QT type the Supersonic would rate 225 or higher, putting it about 90% as fast as the Choate. The SS 27s are normally about as quick as a Holland 25, noticeably slower than a Seaway 25 or Sonata 8. The one from BB was Rascal, which ended up with a slightly bigger rig after the first owner decided it wasn't worth trying to get it down to the QT rating. Did quite well in JOG's fading days.

	. It happens to be a SuperSonic 27. Looking for information and . I have bought it, so please dont tell me that I should have bought something else. to sail four months ago. I was looking for a little that continue to improve my sailing skills on. will be used mainly on waters.

Boat: Pearson 323, Tayana V42CC	. On or in the ? There is another SuperSonic 27 listed in Victoria. Nice looking if the same. Know nothing about them other than the Interweb says Kaufman designed it. If boat is new to you, you can practice by gathering a small amount, say $1000, put it in a small pile in front of you and burn it. The joy you get may be the same as owning a boat. But when you go out for a sail, the is just right, the beautiful and the boat running like she has a bone in her teeth it won't matter at all. We would love pictures if you have them.

And really, your first post asks for info and ... about what? You will find that specific questions get useful answers, whilst vague ones get waffling and off-topic responses that are of little use to you (or others). As example: "Brisbane waters"! I personally know of three distant from each other locations that could be so described. So, where exactly are you talking about? Moreton Bay, near the city of , Brisbane Waters near , New South Wales, or off the city of Brisbane, in Bay? Very different sailing conditions between those places, so differing advice about how to deal with them. There is a huge body of knowledge available here on CF. Tapping it can be tricky, so some care in will reap benefits for you. Good luck, and congratulations on your new toy! Jim

Thoughts on the Ericson 28

Add to quote

So I'm looking at an Ericson 28 that's available through a private party. It's fairly cheap, (under $7,000) but that can be a good thing or a bad thing. My current boat is a 22' swing keel. I'm looking for an upgrade that can last for a few years before we go bigger. I'm having a hard time getting any good information on them. This is the 28, not the + version. My usage is going to be just cruising, no racing. My future plans are along the Washington and Oregon coast, and then to Hawaii and Alaska. It will be myself and my gal. We'll spend a fair amount of time overnighting on it and hopefully a week or two aboard before we take it for a longer trip. I've really had my eye on an Islander 28 (Perry), but they're about twice the price. So what's the verdict? Is the Ericson 28 a decent boat for my goals? Any specific things I should look out for that are known problem areas on it? I'm already taking a copy of the boat inspection trip tips with me before I go look at it.

My first keelboat, “Island Magic” was a 28 Islander. The Ericson 28 and Tartan 27, were the other two I looked at. Very comparable the Ericksons are well made and spacious for the size. All three sail adequately. As stated it is a good boat to learn on and begin a cruising experience. I would consider it coastal however all three are underpowered for the currents in the areas you mentioned . Good luck. Buy the one in the best shape.

Well, I went and looked at it. It's an Ericson 28+, not the standard 28, so it's fractional. But it doesn't have a backstay adjustment, which is odd. One of the things I've heard is that it's a slow boat, and as chef said, underpowered. It's really wide inside! I'm not sure if that's a good or bad thing. There's about 5 feet of space between the settee cushions. It feels huge inside. That's a good thing for the most part, but what about underway in rough water? Pros: Within the last year, new bottom paint, zincs, water and fuel tanks, prop, cutlass bearing. Deck seems solid everywhere and in really good shape. There's just about no crazing of the gelcoat anywhere. I didn't take a moisture meter, so I'm just checking the boat out prior to spending any money getting a moisture meter or a survey. All the hardware was supposedly rebedded recently. Mainsail seems really crisp. The interior has all the headliner and hull liner pulled off, so at least I could see all the wood and glass. I couldn't see any places where there had been any leaks. The bilge had about an inch of water in it. Cons: The headliner has been taken out, and the liner along the hull. He said the head will back up a bit, but not overflow. I'm not sure what that means?? Anyone familiar with that? There's only two sails, the main and a 150% furling genoa. Nothing setup for a spinnaker. Barient winches. So parts will be hard to find. Cushions need to be redone. The batteries were pretty well drained as his wife had accidentally turned off the charger, so he couldn't get the motor to start. He said it has been repowered, but he didn't know much about it. He said the motor runs really well. From crawling under it, the motor seemed clean. No grease or oil around it, no oil or slime in the bilge. It's freshwater cooled. I looked at the rudder post, and couldn't see anything wrong with it, but I didn't check it thoroughly. I forgot to check the keelbolts, I did look in the bilge, but I didn't see any bolts and didn't think to look for them. Obviously this is just a preliminary checkup, I'll need to go through it more thoroughly and take it out on the water if I decide it's worth pursuing. Thoughts?

so far, so good. If the winches turn, then not much to worry about. Barient's are pretty much bulletproof. You can clean and oil them. Backstay adjustment wasn't a standard thing on boats of that type and year. The toilet probably just needs a joker valve or maybe a rebuild kit. Boat toilets are always a touchy thing - you just learn to deal with them and they don't really break the bank.

Thanks for the info. I'm leaning a little more towards getting it. Here's all the pictures I have. One of the slightly concerning things is that they moved the main traveler up over the companionway. This puts the sheets pretty far out of reach, and I'm not sure how strong that bracket is. It seems like a lot of leverage working on it in a blow. Am I being paranoid?

Attachments

More pics. Also, they weren't able to get that B&G Network quad to turn on. Not sure if that's fixable, or how expensive it is going to be to replace. He said all the transducers were replaced this within the last year or two.

And the last pictures.

Vehicle Boat Yacht Naval architecture Sloop

I'm pretty sure that it has encapsulated ballast - I've never seen an Ericson that didn't. They don't have keel bolts. Price seems average at best to me, at least around here in SoCal that would be slightly high in that condition.

Lazerbrains said: I'm pretty sure that it has encapsulated ballast - I've never seen an Ericson that didn't. They don't have keel bolts. Click to expand...

Personally, I like mid boom sheeting. On my previous boat, I had mainsheets to the stern, and had maybe an irrational fear of having a sheet line get wrapped around my neck. If it wasn't original, I would look into it more.

It's not original, which is where my concern is from. In the pictures of the cockpit you can see an empty slot where the mainsheet traveler track used to be right in front of the companionway. So it was previously somewhat of a midboom, but they moved it a little further to the mast. I can actually understand moving it. I'm just concerned about that frame they made to hold the traveler. With it being an upside down U it seems like there would be a lot of leverage on the two attachment points on the end if there were some big winds.

Chainplates both above and below deck What do the backing plates look like under the traveler. Mines on the coach roof but not as elevated. Garhauer makes an elevated system though Lifelines are all sagging. Interior doesn’t look well cared for in terms of upkeep of the teak/ cherry. Not a hard thing to do so how does the other maintainence look...bilge? Is this keel stepped or deck stepped. If keel step could explain water. If not how is there water in the bilge.

Why is the liner out You may have some elbow grease needed for this boat

Deck stepped mast. Definitely cheaper than other Ericson 28s I can find out there. But that doesn't mean it's a good deal. I'm wondering about the water ingress too. According to the seller, the previous owner had been a smoker and the seller is allergic to cigarette smoke, so they've been tearing stuff out trying to get rid of the smell. I'm not afraid of some work, but my time does have value. I don't want to put thousands of dollars in time on something and end up having been better off buying a finished boat.

I would want to find out how the water got in. I sent you a few Eriksons 28+. At least one was coach top main travelor

It looks like the two that had coach top (I didn't know that's what that was called) travelers are 1988s. I think those are Ericson 28-2 models. This one I'm looking at is an '84 28+. The '85 you linked also has a cockpit mounted traveler. They did say that the previous owner had swapped the traveler and had the mounting bracket fabricated out of stainless. If it's done right that's not a problem, I'm just not sure if it was done right. I actually like the 28-2s better, they have wood slat hull liners, and a wood cabin sole. They're also nearly 3x the price of this. My gut is saying to pass on this boat, save up more, spend this season trailering my current boat up to the Puget Sound to get more experience and then next season buy something that needs less work and is closer to what I want. My list of "want" boats is pretty long, but more like: Perry designed Islanders Sabres (especially a 28) Canadian Sailcraft (30?) Caliber 33 Various C&C designs, Tartans And of course I wouldn't kick a Norseman 447, Morris, or Spirit Yacht out of my berth if it were gifted to me. Although the upkeep would be more than my whole boat right now...

Sounds like you arent pushing yourself off that ledge just yet Look around more Trust your gut Learn more

Well I emailed them and told them I'm going to pass on it. They seem like nice folks, I wish them luck selling it. I gave them a few tips to make their ad look better. I think I'm going to stick with my boat this season, set aside more pennies, and watch for a bigger boat that I feel better about for next season. If I could just find a CS 36 freshly outfitted for bluewater for $8,000...

All you would have to do is add a zero to your $8,000 and Voila you would be there. I mean how hard could it be to simply add a zero to sometning ? Zero is basically nothing right?

After looking at the photos and considering that the electronics might not be working right, I think you made a wise decision to pass on this one. Just to give a little perspective on TLC - you want a seller that's been doing the TLC and minimize the effort and TLC you need to put in. 3 years ago I sold a 1975 O'Day 27 for what I paid for it 10 years earlier. It was in your price range. I thought I did well to sell it at that price, and several buyers were tripping over each other to buy it as soon as it hit Craigslist. (Maybe I priced it too low). Not only did I keep up with regular maintenance, I did thousands of dollars in upgrades over the years (replaced the engine with a near new outboard with remote control, new mainsail, pressurized water system, re-doing through-hulls, new running rigging, re-upholstery.....expensive! - new stereo, VHF etc, etc). But those dollars spent were part of the enjoyment of the boat and represented sunk costs, so to speak. Sure, you might not easily find a seller that's transferring a boat in better than average condition, but they are out there. Of course, too many sellers think they have a gold bar - and buyers want to think they steal the boat at an auction price. Somewhere in that delta is where a deal can be made, particularly if you let the seller know that you are going to care for their baby. The closer you get to summer, the more it makes sense to have a 'sail away' vessel rather than a project boat. Keep looking and come back for here for opinions (if you can stand them!). And, good luck.

Thanks. That's pretty close to my thoughts actually. I'd much, much rather buy something that someone is using or very recently used and maintained it. The list of things to do piles up so fast, and if someone is using their boat they are much more likely to fix things. I'm really hoping to find a boat that someone put their heart and soul into, got it ready for a big trip, and then had an unexpected life change and they need to sell the boat. A new job across the country or something like that.

I recently sold my Islander 28 for almost what i bought it for 18 years ago. I maintained it, and upgraded it over the years. People say it's hard to sell a boat. I sold mine in about a week with several offers, maybe priced too low $9800.00, but I know it went to a good family who is keeping her in the same shape I did.

Is a supersonic boat possible?

sail fast How low can you safely fly a plane? The speed of sound at sea level is 340.29 m/s. That is about eight times faster than the fastest hydrofoil. Supersonic flight is an engineering marvel, a topic on which other members can speak much more knowledgeably than me. Considering that that water is 784 times more dense than air, why would you want to dip an appendage into such a medium if the goal is speed? For stability perhaps? Look what happens when you go to the rolling heap for stability at 60 mph (see above websites). Is it possible? I am always the optimist, but why? The forces acting on such an appendage(s) at supersonic speed would be huge, with resultant drag penalties. Of course there is also cavitation to consider. I'm curious, what happens if any solid is moved through water at supersonic speed? How long will it take to dissolve ?

Hydrofoils markdrela said: To allow a meaningful answer, you will first have to define what constitutes a "boat". How about if I take an F-15, and fly very low while dangling a piece of wire in the water? Is that a boat? This is not a silly question. This very issue came up when Doug Milliken was commissioned to write the rules for the DuPont Human-Powered Watercraft Speed Prize, in the late 1980's. It was pretty clear that the fastest way to traverse the speed course would be in a human-powered airplane. To rule this out, he considered all sorts of "boat" definitions. Merely requiring contact with the water was not sufficient, because of the airplane with trailing wire solution. In the end he decided that the boat had to derive a majority of its lift and control forces from the water. Propulsion was left unspecified. This definition worked well for a human-powered boat, but it probably wouldn't be an enforcable for an extremely fast boat. Saying "no air lift" would probably disqualify most current hydroplane boats. How can you prove that air isn't providing a significant amount of lift to the vehicle? Ditto with air fins providing stability and control. Click to expand...

Speed Records Sketch said: How low can you safely fly a plane? The speed of sound at sea level is 340.29 m/s. That is about eight times faster than the fastest hydrofoil. Supersonic flight is an engineering marvel, a topic on which other members can speak much more knowledgeably than me. Considering that that water is 784 times more dense than air, why would you want to dip an appendage into such a medium if the goal is speed? For stability perhaps? Look what happens when you go to the rolling heap for stability at 60 mph (see above websites). Is it possible? I am always the optimist, but why?

Do you mean the speed of sound in water? The speed of sound in sea water is 1,531 meters/sec. So there's lots of "room" between current records and "supersonic." Didn't Russia develop some very fast torpedoes? How fast are they?

The problem is wave making resistance plus the compression of the sound waves the vessel would be overcoming. On the land speed record, a supersonic car went out of control because the shock wave was making holes in the track and violently shaking it.

Silly question, but it is possible, perhaps a WIG (wing in ground vehicle?) http://www.4p8.com/eric.brasseur/swlbi.html (This website's writer says that it is possible to avoid shockwaves!)

Come to my house... Hello... I have a supersonic boat in my garage just now... Come on over - and I will show it to you and my vodka still as well... If I like you - we can get into the sauce and talk about our Martian brothers who await the day that we choose to plug ourselves back into the grid... Sure.... SH.

I had absolutely no idea, I just posted some website that I didn't even read But anyway, let's just say that, for now, it's impossible. Perfect conditions with a flat bottom boat powered by a few jet engines, maybe.

An unmanned submarine is possible, a high-output nuclear reactor powering a vessel using jet drive, no radiation shielding or weapons, just a computer, reactor and drive.

However, a submarine is not a boat so it doesn't qualify.

Review of Sun 28

Basic specs..

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.

The boat equipped with a masthead rig. The advantage of a masthead rig is its simplicity and the fact that a given sail area - compared with a fractional rig - can be carried lower and thus with less heeling moment.

The Sun 28 is equipped with a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a long keel.

The boat can enter most marinas as the draft is just about 1.52 - 1.62 meter (4.99 - 5.29 ft) dependent on the load. See immersion rate below.

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Sun 28 is 1.98, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

What is Theoretical Maximum Hull Speed?

The theoretical maximal speed of a displacement boat of this length is 6.4 knots. The term "Theoretical Maximum Hull Speed" is widely used even though a boat can sail faster. The term shall be interpreted as above the theoretical speed a great additional power is necessary for a small gain in speed.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Sun 28 is about 125 kg/cm, alternatively 705 lbs/inch. Meaning: if you load 125 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 705 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

What is Motion Comfort Ratio (MCR)?

What is L/B (Length Beam Ratio)?

What is a Ballast Ratio?

What is Displacement Length Ratio?

SA/D (Sail Area Displacement ratio) Indicates how fast the boat is in light wind: - Cruising Boats have ratios 10-15 - Cruiser-Racers have ratios 16-20 - Racers have ratios above 20 - High-Performance Racers have ratios above 24 Sail-area/displacement ratio (SA/D ratio): 16.42

Maintenance

When buying anti-fouling bottom paint, it's nice to know how much to buy. The surface of the wet bottom is about 22m 2 (236 ft 2 ). Based on this, your favourite maritime shop can tell you the quantity you need.

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.


Usage	Length		Diameter
Jib sheet	8.5 m	(28.0 feet)	10 mm	(3/8 inch)
Genoa sheet	8.5 m	(28.0 feet)	10 mm	(3/8 inch)
Mainsheet	21.3 m	(70.0 feet)	10 mm	(3/8 inch)
Spinnaker sheet	18.8 m	(61.6 feet)	10 mm	(3/8 inch)

This section is reserved boat owner's modifications, improvements, etc. Here you might find (or contribute with) inspiration for your boat.

We are always looking for new photos. If you can contribute with photos for Sun 28 it would be a great help.

A tough H28 review, but some great information!

Thread starter Tom Boles
Start date Apr 22, 2002
Hunter Owner Forums
Mid-Size Boats

I chanced to find this fellow writing in florida on the topic of yacht surveys. He mostly does powerboat surveys, but appears to know a thing or two about sailing craft as well. His overall site has a tremendous amount of boat and boat construction-related info, and I recommend it to anyone seriously interested in fiberglas boats.The H28 review link is below.(PS: He did not like the boat or the construction!)I'd like to hear what others think.

I posted on this review a couple of months ago. I owned an H28 for about a year and half and found most of the review to be on the mark. Most of the reviewers complaints were the same ones we had and caused us to move up to a larger boat.However, for our purposes, which is coastal cruising, we found the H28 to be a good first monohull boat. Not one we would grow into but a good learning experience.

And What Boats did he like? The author of this article is a very knowlegeble surveyor but when you read all of his reviews (which he has stopped publishing new ones I believe) unless you have considerable monies to spend on a boat, you are out of luck. Remembr a Hunter 290 will cost you about 65 - 70 K equipped. I do like reading his reviews because they provide a lot of useful information.What it gets down to is you get what you pay for and Hunter, Catalina, Beneteau and yes, even McGreagor, fill a market niche. The problem that manufacturers face is putting out boats which have all the amenties perceived by the public as being necessary in a boat and still make them affordable. Then they feel compelled to keep bringing out new models to wet the appetites of those looking for a new boat. If they don't sell new boats, they are out of business.I have many complaints about my Hunter but then I look at a replacment cost and can live with the issues. Then again, my boat is 16 years old and still floats reasonably well. I think you would be suprised at the high percentage of these boats that still give their owners pleasure even even after 25 years of use which is what counts in the long run. Now an Atlantic crossing is another story.

Paul Aubrecht

Pascoe is a little too rigid I have also read a great deal of Pascoe and his articles ona number of topics are well written and full of useful information.However,I think that in regards to his surveys,he is a little too extreme in his views.I think everyone who has any experience with boats knows that a Hunter is not a Cabo Rico and is not the same price either.If Hunter made the boat to Pascoe's standards,most of us couldn't afford it.I have a 93, Hunter 28,and yes some of the stuff he says is true,but after a couple of beers,the floor in the head seems normal to me!!!

There is another SuperSonic 27 listed in Victoria. Nice looking boat if the same. Know nothing about them other than the Interweb says Kaufman designed it. If boat ownership is new to you, you can practice by gathering a small amount, say $1000, put it in a small pile in front of you and burn it. The joy you get may be the same as owning a boat.

Is a supersonic boat possible?
The speed of sound in air at sea level is 340.29 m/s or 761 mph. I thought this would be a more appropriate measure for a supersonic boat as most of it will be above water - a supersonic submarine is a whole 'nother can of worms (1531 m/s is over 3000 mph!) And yes, I was thinking of a water speed record - "How low can you safely fly a plane" was a facetious remark.
The Hull Truth
Well, first of all, I love the boat. Mine had separate people survey the engine and the rest of the boat. The engine surveyor was great. If your boat is between 1999 and (I think) 2002, the Yanmar 6LP-STE should have had the exhaust valve seals replaced with different ones as per a manufacturers notice.
