This Bill Tripp Jr. design is a center-cockpit motorsailer. However, she is also like a modern deck salon before her time. The boats were built from 1971 to 1976 and a total of 180 were built. This boat is hull 12.
The hull is solid hand-laid fiberglass. Hull and Rigging are consistently reported to be “heavy and “stout” by owners.
The topsides give you 5 feet of freeboard which gives you more room down below and fewer swamping waves in heavy weather.
She is a masthead sloop and keel stepped. She has a straight driveshaft set slightly off-center to starboard.
Access to the engine, batteries, diesel, freshwater and holding tanks can be accessed from the sole of the raised saloon.
In addition to the main and jib, there is also an extra jib in good condition, a light wind sail in a sock in new condition, and an extra hank-on storm sail in good condition.
What a great cruising boat with 25,000 lbs of displacement she rides the swells very comfortably.
She has an electric winch forward of the cockpit on the aft top of the cabin house for the main halyard. The self furling jib is handled nicely with a self-tailing conversion kit on 2 Barlow winches on the aft coaming of the cockpit.
She would make a nice liveaboard or cruiser with plenty of space for you and the crew.
For those warmer climates, there is a new frigidaire air conditioner (12,000 BTU) to keep you cool on a hot day.
This model is known for its cross-ocean journeys and adventures.
For those long voyages the auto-pilot will come in handy and 2 AIS VHFs make your presence known to all those around you.
2 staterooms and 2 heads with showers help you end or start the day feeling refreshed and ready for what is to come next.
According to the owner, all systems work as they should. The current owner has spent his time updating and bringing current the engine, generator, systems, and electronics.
His next tasks are cosmetics even though the current condition is good for the age. No big issues.
If you are interested in cruising or just living aboard this is a great yacht don’t miss your opportunity to own hull number 12 of 180 in the limited production Colombia 45.
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 √LWLA more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL
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
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
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
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 Beam1.33)
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)
Raised deck motor sailer was available in full keel and shoal draft versions. A ketch rig was also available.
Same hull as the COLUMBIA 43.

Shoal Draft: 5.25’
