Review of Columbia 34 Mk II
Basic specs..
The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season.
The boat is equipped with 151.0 liter fresh water capacity.
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 Columbia 34 Mk II has been built with different keel alternatives.
One option is a fin keel. The fin keel is the most common keel and provides splendid manoeuvrability. The downside is that it has less directional stability than a long keel.
The boat can enter most marinas as the draft is just about 1.68 - 1.78 meter (5.51 - 5.81 ft) dependent on the load. See immersion rate below.
Another option is a long keel. A full keel provide a better directional stability than a similar boat with a fin keel; on the other hand, better directional stability means also that the boat is more difficult to handle in a harbour with less space.
Columbia 34 Mk II can enter even shallow marinas as the draft is just about 1.14 - 1.24 meter (3.74 - 4.04 ft) dependent on the load. See immersion rate below.
The boat is typically equipped with a Palmer P-60 gasoline engine at 27 hp (20 kW). Calculated max speed is about 5.8 knots.
The fuel tank has a capacity of 114.0 liters (30 US gallons, 25 imperial gallons).
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 Columbia 34 Mk II is 1.75, 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 7.0 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 Columbia 34 Mk II is about 170 kg/cm, alternatively 956 lbs/inch. Meaning: if you load 170 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 956 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.

Rig and Sails
Auxilary power, accomodations, calculations.
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
Sail Area / Displacement Ratio
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64) 2/3
- SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D : Displacement in pounds.
Ballast / Displacement Ratio
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
Displacement / Length Ratio
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
Comfort Ratio
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
Capsize Screening Formula
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
Keel/CB and shoal draft versions were also available.

Columbia 34 Just bought Anyone else have one?
Just bought a 1971 Columbia Mark II 34. Anyone out there have one and want to share information, tips and whatall?  A '74 of the same model You may want to read the posts here: http://forums.projectbluesphere.com/ShowPost.aspx?PostID=63 He bought a '74 of the same model. Consider searching for other posts by the same user at that site, because I believe he started a blog about his restoration projects and process. He definitely liked the headroom... Jim H  From an earlier discussion on the topic, I have some experience with the Columbia 34 Mk II having helped a friend fix one up and then delivering it back to Savannah and daysailed on her in a range of conditions. Columbias (especially during this period) were the Hunters of their day. In other words these boats were designed to provide a lot of space for a low price. Build quality on these boats was quite shoddy. Glass work was heavy by modern standards but because of the sloppy workmanship, laminate schedule and choices of resin was not especially sturdy. There are several serious vulnerabilities in the design of these boats. The 'scimitar' design of the rudder places more than usual loads on the rudderpost and the rudder posts of that era tended to be smaller than are used today on post hung rudders of today. Fatigue in the rudderpost would make it very suspect. The other known problem is with the keel bolts. Many if not all of these boats had galvanized iron keel bolts. If these have not been replaced by a prior owner, the keel bolts are well past their useful lifespan. On the boat that I worked on there were issues with the fiberglass adjacent to the keel bolts that had a serious set of flexure cracks radiating from each bolt. (Invisible to the surveyor at the time of survey but which showed up when the keel bolts were replaced.) Even for their day these were very mediocre sailing boats with a very uncomfortable motion. The rig proportion results in a boat that is not very easy to sail shorthanded and which requires a comparatively large sail inventory. Standard hardware simply was not up to the task of handling the large headsails required for light air performance. These are difficult boats to sail in breeze but especially when the winds are gusty. The full bow and high freeboard resulted in boats that were especially poor in a chop. The website that was linked mentioned the probelem with insuring older boats. This is a very real issue. Several years ago the insurance industry noticed disproportionately large claims on damaged older boats. The industry had noticed that impact damage to the hulls of older fiberglass boats was far more extensive than would normally be anticipated. In the study, sections of actual hulls from older boats were distruction tested for strength. The results of this extensive testing showed that the techniques and materials used during this era were partiaularly prone to fatigue and lacked the strength of more modern laminates. While the results varied with manufacturers, for the more common high production builders (Columbia was specifically cited) the choice of accelerators, large proportion of non-directional laminates, and resin rich ratios, resulted in a particularly poor initial impact resistance (despite the thickness of the laminate), which was shown to deteriorate dramatically over time. This makes it especially important to inspect high load areas for flexural fatique damage. Respectfully, Jeff Jeff, given your last post on Columbias/age of boats.... Jeff, you mentioned that older boats (and I don't know if you were referring only to columbias or also to other boats of that era) were vulnerable to fibreglass problems due to the layup process. Aside from getting a good survey of an older boat before purchase, do you have an opinion, based on your experience, as to what age becomes suspect in an older boat--ie. should one avoid buying a boat built before 1975, for example, because of these kind of problems. I am asking because one often reads that fibreglass boats if well cared for can last almost forever; however, others have written that all fibreglass boats absorb water over time, and will gradually deteriorate/delaminate. I have been looking at 1970s and 1980s boats for my next purchase--Ericson, Aloha, C&C, Crown are high on my list of possibilities. While I would prefer to get a 1980s in really good condition, there are some very nice 1970s with rebuilt engines, replaced standing rigging & sails, that have tempted me--should I be staying away from these in your opinion? I also welcome the opinions of others, if others want to comment. Thanks, Frank. I also bought a 1971 columbia 34 mkii trying to fiind out info on v drives  It's probably a Walters - it was on my 43 and every engine shot I've seen of that series of boats had the same looking V-drive. I have a Columbia 32 from about the same area (1976) and it has a Walter V-drive, too. Works great. For all questions, Columbia, look at columbiasailingyachts : Columbia Sailing Yachts
