Edey & Duff Stone Horse, 23 ft., 1982 Oshkosh, WI - $8,500
My 1982 Stone Horse sailboat (Hull #125) is now available, as I have purchased a larger boat.
She sails beautifully and has classic looks to match!
23 ft on deck - 7 ft beam - 3.5 ft draft - 339 sq ft sail area - 4490 lbs. 5kW Thunderstruck electric inboard conversion 4 years ago - 48V with charger 4 - 100amp hour AGM batteries in 2 battery boxes each side of motor Marine 110V shore power with cord and separate 12V AGM house battery w/charger New mast in 2011 Mainsail Stack Pack system for hassle free sail handling Roller furlers on both staysail & yankee jib allows quick and simple setting/furling Teak cockpit and trim New Total Boat topsides, deck, and bottom paint 2019 New Sunbrella cabin and cockpit cushions 2018 Alcohol stove, icebox, and manual pump sink Portable toilet under one of the 2 most comfortable seats you’ll find on any boat Interior wood panelling reflects the glow of 2 brass oil lamps 9 interior storage bins, large bridgedeck storage area Canvas cockpit awning - swim ladder Jack stands for winter storage - shrink wrapped every winter I’ve had her
I wanted a bigger boat but the Stone Horse is so handy under sail and performs so well in all aspects underway; I wish there was a 30 foot clone of her! Come take a look or contact for more photos/video.
I might consider a smaller, traditional sailing dinghy/daysailer on a trailer of near or equal value in full or partial trade

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
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)
At least 30 built of wood since 1931. Adapted for Fiberglass construction in 1968.(Edey & Duff).
