Seller's Description
Fiberglass reproduction of Herreshoff 12 1/2 daysailer: 1986 “Doughdish” built by Edey and Duff.
If you know these boats, enough said except to note that it is on a Triad trailer and has: custom canvas winter cover and newer cockpit cover. Sails are not fit for racing but fine for day sailing. Other than that, it’s always varnished in the spring but sheer strake really should be stripped and re-varnished. The trailer is a 2005 and is a transport and storage trailer; trailer never goes in the water as it is not really usable for launch and retrieval (full keel, draft of 2 1/2 feet) so you will have minimal yard bills for launch / haul out. Trailer got new tires (3 including spare), bearings, and spares including a set of bearings and spare hub prior to move to North Carolina from Connecticut last November.
Boat is in the water now in Oriental, NC and can be seen there by arrangement as I live two hours away from the boat. If interested in acquiring this fall I will pay for haul out, bottom wash and see that boat is secured on trailer for transport by hauler of your choice. All pictures are recent except for the first one and pictures of the boat on the trailer.
If you don’t know about these boats, let me tell their strengths as I see them. This is a 1,500 pound boat that handles chop and wakes like it weighs five tons. It feels like a little ship but you can take it home for the winter and step and un-step the mast by picking it up. You sit in the boat (on teak benches), not on it, and when you walk forward to handle halyards you walk inside the boat on a teak cockpit sole; you can then seat yourself (instead of balancing on a cabin top) and raise sail sitting down. Spars are spruce and you don’t have to handle aluminum, look at it, or hear halyards slap (they do get 2-3 coats of varnish every spring though).
They comfortably day sail 4 people with more room in the cockpit than most 30 footers. They have the old school virtues of big main and small self tacking jib (no winches).
Equipment: Honda 2.3, autopilot, newer cockpit cover, custom winter cover, all sail covers.

5.4 kn
Classic: 4.74 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
-
24.8
>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
- ?
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
-
228.8
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
-
10.3
<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
-
2.4
>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
A redesign of the original HERRESOFF 12 1/2. Modifications include the addition of a centerboard and slight widening of the beam. Most have been built by individuals from plans, but a completed fiberglass version was available at one time. Gaff and Marconi/Bermudian sloop versions.
