Three sails (genoa jib, mainsail, and mizzen) and covers in good shape, extra roller-furling headsail and hank on staysails/storm sails, all in good condition. Yanmar 3GM30F diesel motor in excellent shape, new starter battery March 2025, no known issues. All tools and plenty of spare parts included. Running rigging in good condition, standing rigging stainless with Sta-Lok replaceable fittings in good condition. New bobstay (S.S. chain) and new bowsprit built of Cruzan mahogany February 2025. Main anchor is 30 lb Bruce type with 100 chain and 250 nylon rode in good condition, spare 40 lb plow, chain and rode included. Bottom paint new in 2022, in good condition scraped and cleaned throughout spring of 2025. Brightwork in great condition maintenance coat of Cetol completed March 2025.
Interior is in very good condition comfortable cruiser and liveaboard. Very clean, plenty of ventilation from two overhead hatches and opening portlights, cushions in great shape. Gimbaled propane 2-burner stove with safety valve and spare propane tank, large icebox, salt and fresh water faucets in galley sink, generous storage. Head and holding tank functional and clean. Galley table converts into double berth. Teak and holly cabin sole. Numerous fans and lights to make the space well-lit and comfortable throughout. Cockpit cushions, backrests, and table included for dining on deck.
Achilles dinghy has seen use but doesnt leak air. Slight water leak in soft bottom but never been a big issue. Yamaha 2hp engine starts on first pull recently cleaned carburetor and inline fuel filter, runs 50:1 premix. Also comes with bailer, pump, and oars.
Mooring is privately owned hurricane mooring and comes included with purchase of boat.

Calculations

6.4 kn
Classic: 6.57 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
-
15.3
<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.
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
-
35.0
<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
-
386.8
300-400: heavy
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
-
36.6
30-40: moderate bluewater cruising 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
-
1.6
<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.
Formula
CSV = Beam ÷ ³√(D / 64)
- Beam: Width of boat at the widest point in feet
- D: Displacement of the boat in pounds
Notes
Originally designed for Kaiser Gale Force Yachts which sold the molds to Allied Boat Co. After changing the cabin top and port arrangement, the first boat appeared in 1962.
Early builders under contract were Lunn Laminates of Port Washington, NY and F.L. Tripp & Sons, Westport, MA.
(Allied eventually had it’s own large plant in the Catskills, NY.)
The SEAWIND was the first, as well as one of the last, boats built by Allied Boat Company. In 1978 it was brought back into production and actually built simultaneously with the newer SEAWIND II.
Also offered with a sloop rig. (with mast stepped farther aft.)
I: 35.58’/10.84m
J: 13.16’/4.01m
P: 31.83’/9.70m
E: 14.25’/4.34m
