Boat is located in Greensboro, North Carolina.

1973 Yankee Seahorse 24ft Sailboat with Trailer.

I am offering an exceptional opportunity to those that sail or wish to.

This 1973 Yankee Seahorse sailboat has been restored to better than new condition.

I have enjoyed over 15 years of sailing at Belews Lake, the Carolina coast and its inland waterways.

This sailboat boasts a v-berth that sleeps two, with a Bomar deck hatch for gazing at the stars, nautical brass lighting on each side, an electric oscillating fan, built in storage and 110v electrical outlets.

On the port side, just aft of the v-berth is where the large portable head is located, nestled in its own compartment, equipped with a solar and battery powered through deck vent fan.

Just to the starboard is a built-in microwave oven with an open storage locker just below.

Moving aft is where the Galley and dinette is located.

The galley is on the starboard side and is equipped with a sink, faucet and hand held sprayer with running water, two burner alcohol stove and several cabinets for storing dishes, pots, pans and several drawers for silverware and such.

The dinette is to the port side of the galley.

The table is a good size with rails to keep things from falling off during those gusting sails when the boat is heeled and the table also comes down to make a nice area for lounging.

The AC and DC electrical panels, marine stereo/CD player, marine communication radio, nautical lighting and electrical oscillating fans are also located in the dinette.

Below the seating is where the dual marine battery system is, with a manual battery selector switch and DC outlet.

Behind the aft back rest is a compartment housing the marine dual battery charging system with room for additional storage also.

Equipment: Behind the aft back rest is a compartment housing the marine dual battery charging system with room for additional storage also. Just aft of the galley there is a TV/VCR mounted on an adjustable swing arm and below a built-in DVD player, AC controls and the output vent for the marine air conditioning system is located in this area also. There is a quarter berth located on the starboard side just aft of the galley which also has storage below. The marine air conditioning system is toward the aft in the quarter berth with through hull intake and outtake. The roof of the cabin can be raise and enclosed with sunbrella to have 6 feet of headroom. Moving aft out of the cabin is the cockpit. On the outside of the cabin there are mounted speed gauge and depth finder/fish finder. There is a built in handheld shower for rinsing off after swimming or strolling on the shore. The foresail and mainsail lines all run to the cockpit. I have six sails for the boat, all in good condition with reefing points, and for motoring there is an 8hp Yamaha four stroke long shaft outboard. The mast can be lowered and raised by a single person even while underway, as needed if one must go under low overpasses. The sailboat has a shoal keel with a swing down keel built in. The rudder and tiller is one unit that can be raised to decrease her draft. Overall she has a 2.5ft. draft with the swing keel up. The trailer has been improved to self-center the boat upon retrieval, is equipped with a 10ft add on tongue extension for use if water levels are low, polypropylene rollers, new axle and load range D tires. I will be glad to answer any additional questions that may arise, dont hesitate to call, txt or e-mail. I have included several pictures and can send additional ones to those interested.

Hull Speed
7.6 kn
Classic: 5.99 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.


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

7.6 knots
Classic formula: 5.99 knots
Sail Area/Displacement
16-20: good 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.


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: 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.


Ballast / Displacement * 100

<40: less stiff, less powerful
>40: stiffer, more powerful
100-200: light

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
<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.


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 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.


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
