Seller's Description

WOW! Don’t Let This Beautiful, Spacious, Solid Sailing Vessel Pass You By!!!

With the large flush deck, spacious interior and a bulletproof hull construction, this stunning Columbia 50 is a real head-turner!

She has been completely re-done and made to be more functional, easier to sail single-hand, and is capable of sailing anywhere.All the hard work to restore this beautiful vessel has been done and she comes with everything necessary to finish the work I’ve started. The interior was stripped and completely rebuilt from the hull up. While the galley/dinette was never finished, it is still functional.

Everything else has new bulkheads,which were done with West Systems epoxy. This boat is stronger and lighter than the original “drop-in” interior liner that she was built with.

Also, the rebuild freed up more usable spaceproviding a functional interior that makes all working systems onboard easy to access

There is brand new wiring throughout the vessel - completely re-wired with all new components, switch panel, swithes, bilge pumps, bus bars, etc

There is also a new Victron Charge Controller and Bluetooth battery monitoring system

The re-designed cockpit layout (winches, rope clutches, traveller, etc)now allows for single handed sailing.

Standing Rigging - Age and Condition:The keel stepped mast was re-fit 2 years ago. New wiring, tangs, Sheaves, lights, antenna, Harken mainsail track and paint. Standing rigging was replaced 4 Years ago, mostly Haynes Hi-Mod compression fitting. All chainplates were replaced 2 years ago before stepping the mast, They are titanium chainplates from Colligo Marine

Running Rigging - Age and Condition:Mostly synthetic lines (Dyneema core w/nylon cover), about 2 years old and in very good condition. She needs a secondary Jib/spinaker Halyard run through the mast.

Winches:2x Barient 32, 3x Barient 28, Barient 24, 2x Barient 10are all in good shape. Thelargercockpit winches can be converted toself-tailing

Included in the sale is aSimrad Multi-function display as well as Simrad Autopilot system that has not yet been installed.

There is also a new Maxwell RC10 Windlass which is ready to be installed

In addition, she comes with a Harken Mark IV Furling system and all necessary components and sail to install a staysail rig.

Many additional miscellaneous new parts, spare engine parts, cleats and deck hardware, blocks, lines, materials, etc. will also be provided to a new owner. However, these will not be inventoried.

The owner is only selling because they purchased a new vessel. Priced to sell - over $10k below current value - because there are still some ongoing projects. This very generous asking price is in hopes that a motivated and enthusiastic new buyer will take these over and finish the restoration.

She will make an INCREDIBLE liveaboard, inter-island cruiser or South Pacific voyager!

Hull Speed

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

A 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

7.45 knots
Classic formula: 7.73 knots
Sail Area/Displacement
<16: under powered

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.
<16: under powered
16-20: good performance
>20: high performance
>40: stiffer, more powerful

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

<40: less stiff, less powerful
>40: stiffer, more powerful
>350: ultraheavy

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
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
40-50: heavy bluewater boat

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 Beam1.33)

  • D: Displacement of the boat in pounds
  • LWL: Waterline length in feet
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
Capsize Screening
<2.0: better suited for ocean passages

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)

  • Beam: Width of boat at the widest point in feet
  • D: Displacement of the boat in pounds
<2: better suited for ocean passages
>2: better suited for coastal cruising
