BOOMS WITH A STRONG PROFILE

Seldén booms have a wealth of sophisticated features and can be equipped with a variety of reefing systems to suit different boats and the needs of different sailors. The booms can be fitted for traditional slab reefing or Single Line Reef, or be used for furling masts. The boom extrusions are relatively deep in relation to their width, allowing a lighter extrusion with high resistance to vertical bending. This makes them perfect for use with modern, stiff sailcloth and efficient Rodkicker rigid vangs.

WHY YOU NEED A NEW BOOM

The most common upgrade is to a Single Line Boom. Remain in the cockpit and pull one line to reef your sail and you will prevent adventurous maneuvers at the mast. It’s quick, safe, easy to handle and convenient.

It’s full of potentials. A new boom is prepared for Rodkicker, Lazy jack sliders, easy installation of a stack-pack system and boom light that will lighten up your cockpit at night.

MAKE IT HAPPEN – IT’S EASY

To decide what you need, here are a few useful steps:

Check if your boat is listed here . If it is you will know what size boom we recommend and its part number.
Find out how stiff your boat is by calculating the Righting Moment (RM) at 30° heel. This is done with our calculator .

Click on technical information below and use the dimensioning table for Masthead rigged boats or Fractional.

You need to know the RM, the E-measurement and the Y-measurement to make your choice and all those measurements are explained in this area.
Compare the forward end of the Seldén boom to the dimensions of the boom bracket on your mast. Clevis pin dimensions and width and depth of the forward end.

Or… just ask a Seldén dealer to figure it all out.

LIGHT BOOMS IN CARBON FIBRE

Seldén supply carbon booms that harmonise with its carbon mast range. Carbon booms offer weight savings of up to 35% compared to aluminium. This means that boom weight on a typical 35 ft boat is reduced from 30 kg to just 20 kg.

A lighter boom makes gybing less dramatic, as the boom has less momentum. This has a positive effect on the whole boat, especially with regard to the service life of the mainsheet attachment.

A lighter boom also reduces the tendency of the boat to roll when sailing downwind and it improves the effect of the Rodkickers’ gas spring. The section modulus of a carbon boom is twice as high as that of an aluminium boom with the same weight per meter. A stiff boom makes for improved trim and thus higher boat speed.

Boats that sail IRC, and which are already fitted with a carbon mast, suffer no further rating penalty by up-grading to a carbon boom.

In order to reduce weight, while still providing sheaves for single line reefing, we have made the inboard end fitting as short as possible. The outboard end, which is integrated into the carbon section, is finished with a carbon cover plate.

The mainsheet block is attached using a Dyneema® strop that passes through an aramid tube in the boom. Stainless steel bushings at either end of the tube prevent wear, while local carbon reinforcement provides the extra strength required. Booms with “German” split mainsheet systems have fastening positions for blocks at the inboard end, and two webbing strops to hold up the mainsheet.

The carbon booms feature hand laid local reinforcement in the vang attachment area.

Carbon booms can be supplied ready for conventional slab or single line reefing. Clutches can be integrated into the inboard end if you do not wish to lead the reef lines to the cockpit.

The standard Seldén outhaul system features a Dyneema® outhaul line for leading back to a winch in the cockpit. As an alternative, an internal cascade system with up to 20:1 purchase can be used and operated by hand from the cockpit or by a crew member hiking on the rail.

BOOMS FOR DINGHIES

Seldén dinghy booms have been designed to offer the ultimate in stiffness, weight and functionality. From single-line reefing systems to high-purchase internal outhaul systems, Seldén booms can be equipped with a range of sophisticated features that will make your sailing easier, faster and more convenient. Class rules are closely studied to push performance to the limit. For example, the Olympus boom section optimises the 470 class rules to give the lightest and stiffest boom the class rules allow.

All sections are optimised for high resistance against vertical bending and come with an integral sail track and lower in-boom track for mainsheet and kicking strap attachments.

Cheap boom replacement ideas for small sailboat?

Add to quote

I am looking for the cheapest way to (safely) replace the boom on my 16' Melges sailboat. I understand that sailing is not the cheapest hobby, and maybe someday I will be able to afford a new boat, but for the time being I would really like to do the best I can with what I have. I bought the entire boat in as-is (poor) condition for $100 last summer, understanding that it could sink on the first day. With a few DIY repairs, it sailed beautifully all summer, until the homemade wooden boom began to split from dry-rot. As a $100 boat is not worth a big investment, my goal is to spend the minimum amount of money necessary to keep my boat on the water and sailing. Fully rigged booms can be purchased from the Melges website for just under $500. Does anyone know if/where it is possible to purchase a generic boom (approx 10-12')? Is this even a good idea, or would I spend just as much rigging it in the long run anyway? Anybody tried making a boom? I have limited tools to work with, but I'm not afraid of a little hard work, and despite all the information the internet offers, I have found very little to answer any of the above questions.

honestly, with limited funds, and limited tools, the $500 boom with hardware is looking pretty good. Add in what your time is worth, and it becomes a fair price.

i would take a minute to consider weather or not your boat is in danger/nearing another serious failure. just hate to see you drop five hundo to have something else break for another five hundo etc... at some point you may want to consider 'hmmmm... how much am i willing to sink into this as opposed to using the funds i would have spent on repairs to get something in better shape.' just a thought, good luck

3" pvc schedule 40 pipe. attach the main as a Loose foot,

Go schedule 80..it's stronger... heavier too... but if you're going cheap...sch 80 makes more sense.

great ideas Going with PVC definitely sounds like it's worth giving a shot. QuickMick sums up my feelings pretty nicely, I don't want to drop $500 on a new boom only to have the hull disintegrate on me a few months down the road. I wasn't even aware that the main could be attached as a loose foot, but this would certainly be much easier (and more in the range of my DIY skill level). For a loose footed attachment, is the sail only connected to the boom at the clew? I've been browsing other posts, but I'm not seeing anything that makes this completely clear. Anyway, thanks for the great advice, and wish me luck!

I would price out a piece of Aluminum Tube before going with the PVC as its pretty flexible even in #80 and will be hard to fasten stuff to it compare to Aluminum as you should be able to get a hunk for about 60 bucks

Dwyer Masts has extrusions and fittings for not too much money. Get the parts and assemble it yourself. Would probably be over 100 though, but less than 200.

Another option is to find a boom off another boat used and cheep. A laser mast could be retrofitted, perhaps a hobie mast or boom. Look for a bombed out hull in the local club (ours cut up a few last year with a chainsaw) and see if they will part with the spars for less.

You specified the cheapest. Many thousands of small working sailboats go to sea with a sapling for a boom.

Using the aluminum tube inside Fiskars tree pruner. Took cutting blade and chain off, mounted to piece of epay wood then u-bolted to 2" Bic Melody mast. Bic sail replaces giant sail that comes with my Force 5 So I can get under railroad bridge and the raise entire rig while on the water. 16 foot Bic mast is fiberglass and being for a wind sailer is easily lifted. Cutting head has a 160 degree adjustment with lock off. This will replace the vang. Flat nylon cord is the out haul using the included roller at the outer tip. 2 chrome tie downs riveted along with 16 inch by 1 aluminum strip that hold the harken rollers for the main sheet. Might add a real vang if lock off doesn't hold. Weight about 1 lb.

As this is a five year old thread I guess the OP has fixed it by now.

Boom Replacement on M384

Your boom looks like mine on the 382, in design though not length. Amazing the slider won't budge, but 30 years of corrosion works wonders. I have never heard anything good about RigRite, but neither have I ever used them. Curious they can have that reputation and continue. I have used Rigging Only to replace my standing rigging. Great folks to work with. I would love to come over and see the new boom when it arrives.

Mark, I also got the US spars boom. It is the model Z362. I ordered it with 4 jammers in the forward lower section, 7 under boom cars for the vang, main sheet blocks, and three reef points. I had to make an outhaul 7to1 and changed the main to loose footed rather than change the boom slugs. I got the boom with the under boom cars loose in the bottom track so as to be able to fit their positions exactly. I am very happy with the boom.

May 25, 2015

Hi John - sorry for the delay, I've been on a big boat trip ... I'm curious - how did you handle the gooseneck fitting using their Z362? Did you replace the fitting where it attaches to the mast? Or use your existing fitting? If you replaced it, did you have problems getting it off? Thanks!

Jeff Lovett

Mark, What is the latest on your boom replacement. I am eager to learn more about your installation and your thoughts on the Z362. Pilgrim needs a new boom. The PO installed a new double spreader rig matches the M383 & 384 specs and moved the main sheet to the cabin top / mid boom. Unfortunately the PO kept the original boom. The original M382 15' boom is not strong enough to handle mid-boom sheeting. Have found a used boom off a circa 1980 C&C 39 that matches the specs we need for Pilgrim, but the boom needs repainting, new goose neck, new mid mast bails, and likely a new sheave box at the aft end. I'm thinking by the time I buy the parts and do the repair / modification work I would be into the used boom for about what you spent on the new Z362.

Sep 22, 2015

Hi Jeff - sorry for the delay. We are on a big road trip & almost no time to jump on web. Our boom replacement went very well. US Spars was a joy to deal with and when we received our "blemished" spar we were very pleased that the blemishes were so tiny you wouldn't even notice them unless you were hunting for them. It is a joy to have a nice, new shiny boom on Zia. I would for sure do that again rather than stripping, then painting, refitting an old boom. I'll put some pictures up when I get home. The new boom doesn't look to be as rugged as the original Kenyon spar, but I'm quite sure it is plenty rugged enough for anything I'll need to throw at it. If anyone needs a gooseneck fitting - I will be cutting mine out of the boom tubing and selling it. It was recently fitted with new sheaves, cams, bolts, and jam cleats from Rig Rite ($240 for that hardware). I'd sell the whole assembly for $200 ... RR sells them for $890. I'll send pictures if you are interested. Cheers, -Mark

Marvin (Bill) Williams

I'm Interested. When you get pictures, how about sending to me at s [email protected]

Sep 24, 2015

OOPS. Mark, just removed my head from a dark place and realized that the boom sections are different for your 384 and my 382. So, disregard my comment about interest in your gooseneck fitting. Bill Williams

That's one good-looking boom, Mark!

Mark - Thanks for posting the images. The boom looks like a wonderful upgrade.

Time for a reality check....... I'm seeking quotations for a carbon fibre boom. So far they range from $9700 to $6900. I have a carbon fiber spinnaker pole which is truly a delight. So am I nuts?

Hi John - yes, I think you are nuts. Full disclosure: I've spent more money than that on things that were nuts and still had fun with them. I think you get a lot more intimate with a spinnaker pole, constantly moving it using mostly man/woman power. I can see the allure of a super light Spin pole. The boom, though, is always suspended on other spars/lines. It's not super high so the 'reduce weight aloft' argument doesn't work. My Aluminum boom doesn't weigh that much - I'm guessing 40 lbs. I'd guess a CF boom might save 10-15 pounds? In my case, if I had those $$ to blow, I'd go take an exotic vacation for a month at a spa, and lose 10-15 pounds off of me instead;-) Cheers Mark

KISS-that also means spending reasonable amounts to maintain and improve a boat, that is unless your Trump or Gates.

Oct 21, 2015

I don't have any direct experience, but I've heard that when lightning strikes a carbon fiber spar it explodes due to the insulating properties of the epoxy. Other than that and the cost I can't think of a single disadvantage.

Steve, A local JBoat, 130 model I think, with a carbon fiber mast was struck by lightening in summer 2014. The owners, fearing the lighting compromised the spar, stepped the mast and had it inspected. Not sure by whom or by what process the mast was inspected, but it was decided by the owners & their insurance company the spar was intact. The mast was re-stepped into the vessel. I think that any mast suffering a direct lightening strike needs to be closely inspected for damage. John, I agree with Mark on his assessment. Can not see the benefit of spending thousands of additional dollars for the weight loss on the boom.

Thanks, Jeff.

James M. Cleary

A friend of mine with a 1986 Freedom Cat Ketch was hit by lightening 2 years ago. All his electronics were fried. The insurance paid for all that. This year the bottom 6" of his carbon fiber fore mast has disintegrated. The mast was not inspected after the strike for structural damage. Now the insurance company refuses to pay for the mast to be replaced. He is going to be on the hook for a $40,000 mast. Be sure to choose your surveyor well if you get struck by Mother Nature. Jim

Oct 23, 2015

But wait...There's more The latest quote from Aspire Spars of Cleveland Ohio (aka Tartan Yacht) was for $3920. Our existing boom is a US Spars salvaged from a Beneteau about 20 years ago when we converted the 382 to mid boom sheeting. It's Twice the mass (at times it seems to be made of depleted Uranium) of the end of boom sheeted OEM Kenyon and is way past the replacement time. The Admiral is in favor of it because we double hand in the SF bay and when we de-rig the boat every year the long haul up the ramp to the storage yard is more and more a struggle. Anything can be justified. Photo blog to follow........... John

OK, I've got my Nomex suit on!. It was delivered undamaged in a 5/8" Philippine mahogany crate that weighed almost 100 pounds. I didn't weigh it but the Admiral is able to lift it by herself so that's the metric fulfilled. Jibes are akin to a dinghy. No scratches yet.

I've just yanked it of the boat for the summer anchor out. There is not much hardaware on the boom execpt for exit blocks. The mid boom mainsheet bocks are attached by dogbones inside the boom with dyneema loops sticking out the bottom. Probably have the weight by the week of the 16th. You could will call that at the Taratan Yard just east of Cleveland. Shipping was $650

Technical Specifications
Boomkicker K1000 Installation Instructions

Manufacturer part #: K1000 Boomkickers use two coated solid fiberglass spring rods to provide the force necessary to support the boom and mainsail. The rods are clamped into teflon anodized aluminum end pieces and attached to universal mast and boom fittings. Fittings are included along with machine screw fasteners, the proper drill and tap and hex wrench. The mast fitting includes a round slide which, used in the luff groove, avoids drilling into the mast. Flat slides in varying widths are available from the factory. The slides can often be inserted at the sail opening above the gooseneck and slid down reassembling the fitting in position. If slides are not usable, the fitting can be attached directly to the mast using the same drill and tap provided for the boom. The custom extruded boom track is contoured to fit both round and flat bottom booms. The track has an adjustable clevis pin to set the maximum height the Boomkicker will lift the boom. The track length forward of the pin allows the boom to move higher if needed.
