Columbia 50
Columbia 50 is a 50 ′ 0 ″ / 15.2 m monohull sailboat designed by William H. Tripp Jr. and built by Columbia Yachts between 1965 and 1972.
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)
When introduced in 1965, the COLUMBIA 50 was the largest production fiberglass sailboat available in the US. Also sold as bare hull or ‘kit’ under the SAILCRAFTER name. Sloop, yawl or schooner rig. (In the early 1980’s, the molds were acquired by P&M Worldwide Inc. which offered the boat in kit form. If any were made is unknown.)

Cruising Boat Spotlight: The Columbia 50
By: Pat Reynolds Cruising Tips , Sailboats
In our new series of great cruising boats we begin with a crowd favorite – the Columbia 50. With its bubble top, long graceful lines and inherent speed, the Columbia 50 is a beloved classic.
Designed by Bill Tripp, the Columbia 50 was sexy, fast and fun when it came off the line in 1965. Fiberglass boat building was still relatively new, but Tripp was ahead of the curve as he had been designing fiberglass boats since the late 50s. In 1966 the lean racer/cruiser won the legendary Newport to Ensenada race in California, which, at that time, was over 500 boats. The boat was built predominantly by Columbia Yachts in California and was the largest fiberglass production boat of its day.
Next time you see one of these elegant specimens heading out to sea, realize that they are more than a pretty face. The Columbia 50 is a pioneer design in that it was the first big sailboat that didn’t cost an absolute fortune to build. Much labor went into wooden boats of the day and the 50 opened the door for more affordable big boat sailing.
Today, the design still holds up – both structurally and aesthetically. Fifty-seven boats were built and many are still kicking around (check out the Columbia 50 Owners’ Network ), especially on the West Coast of the U.S. Since fiberglass boat building was new in the mid-sixties, boats of this time were usually overbuilt (by today’s standards) and therefore are pretty tough.
As for picking one up on the used market, they’re not a dime a dozen and they’re not really cheap ( Columbia 50s for sale ). The Columbia 50 seems to have achieved a classic car sort of status based on its good looks, solid build and limited quantity (unlike the more abundant Columbia 26, that looks similar but are more abundant and pretty inexpensive). Most Columbia 50 owners will tell you that this boat is an ageless beauty that performs just about like a modern boat. It’s happy racing locally or venturing out into the open ocean, but wherever it is you can bet she’s turning heads.
Torben Grael is arguably one of the finest sailors in the world. This photo shows his Columbia 50 together with his Star boat. He is an accomplished sailor ( see Wikipedia ) winning several Olympic medals in the Star, and winning the Volvo around the world race in 2009. Great sailors like great boats!
