Seller's Description
Go to Sailing Texas classifieds for current sailboats for sale Herreshoff America 18 Catboat sailboat for sale in very good sailing condition with 5-Star trailer and tabernacle mast.
Boat last sailed in Maine and Buzzards Bay during 2022 season. Everything works as it should, very easy to setup and launch. Tabernacle mast can be rigged in about 5 minutes or less with one person (easier with two). Launching and recovery from the trailer is very easy. Engine starts, runs, and idles perfectly - two cylinder 4-stroke is very quite.
New work completed 2021/2022:
Tan Bark reefed sail Running rigging Electrical system (all wiring/AGM 100 AH deep cycle battery/running and anchor lights) SIMRAD Cruise chart plotter and depth sounder Two 10-gal polyethylene drinking water tanks Bilge pump Fully serviced 8 HP Yamaha outboard in motor well (lower end rebuilt with all new gaskets/fluids/zinc; oil changed; water pump impeller and gaskets replaced) New Laveo Dry Flush toilet ($800 - you will never look at a Port-a-Potty the same way) New cockpit grating and newly varnished seating New laminated tiller New manual trailer winch
Included with sale:
Cockpit cushions; fitted sail cover; primary winch; anchor/chain/rode; swim ladder; boat hook; coast guard safety pack; cockpit cover and tent; dock lines; fenders; spare trailer wheel; etc. Clean MA titles for boat and trailer.

Calculations

6.7 kn
Classic: 5.65 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

22.6
>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
-
20.0
<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
-
199.6
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.
Formula
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
- Comfort Ratio
-
13.4
<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
