Seller's Description
This boat is a real beauty, in very good condition and ready to sail. She was owned by a board member of the Landing School in Arundel, ME for many years. The current owner bought the boat several years ago with the intention of making her as close to as new condition as possible. The topsides were repainted flag blue Awlgrip by Portland Yacht Services in 2022. Following a summer of light sailing in Rye Harbor, NH the boat was brought to Areys Pond where it was given a generous facelift. The cabin top, deck and spars were all freshly painted. Non-skid was added where necessary on the cabin top to mitigate slipping on the curved surface. A new low-profile hatch replaced the old hatch. New halyard organizers and a self-tailing winch were added for ease of raising the peak and throat. The port rub rail was replaced and bronze half round was added all around the rails. Winter of 2023-2024 Portland Yacht Services redid the flag blue topsides due to scratching from a mooring pennant. The motor is as close to new as possible with less than 10 hours on it. Sail is a tan Quantum sail in very good condition. Interior and exterior cushions are all in very fine shape. Navy blue exterior cushions are Sunbrella and interior cushions are grey blue. Included are Quantum Tanbark sail, sail cover, cushions, compass, bronze bell, VHF, running lights, fire extinguisher, Tohatsu 2024 long shaft 6HP SailPro motor and 1985 EZ Loader trailer. For more information or to schedule a viewing please call Arey’s Pond Boat Yard at 508-255-0994.
Equipment: New self tailing winch. New Tohatsu 6hp sail pro outboard. EZ Loader trailer with new bearings as of 2023.

Calculations

6.8 kn
Classic: 5.76 kn
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.
Formula
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
- Sail Area/Displacement

21.3
>20: high performance
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.
Formula
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
-
20.7
<40: less stiff, less 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.
Formula
Ballast / Displacement * 100
- Displacement/Length
-
204.3
200-300: moderate
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.
Formula
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
- Comfort Ratio
-
14.9
<20: lightweight racing 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.
Formula
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
- Capsize Screening
-
2.3
>2.0: better suited for coastal cruising
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.
Formula
CSV = Beam ÷ ³√(D / 64)
- Beam: Width of boat at the widest point in feet
- D: Displacement of the boat in pounds
Notes
Inboard Diesel engine available as an option.
A later version was called the THOM CAT 19.
