The Dickerson 37 aft cockpit ketch is a handsome cruising vessel with many practical features; wide decks, safe bulwarks, nav station, large comfortable cockpit. New teak and holly sole with 7 coats of varnish. One of George Hazen’s best modern sailboat designs using state of the art computer technology with a modified full keel and skeg hung rudder provides exceptional sailing performance. Ideally designed for the shoals of the Chesapeake, the ICW, Florida and the Bahamas. A beautiful ketch at a reasonable price.
Equipment: Rebuilt Perkins Diesel (2020), new running rigging, new batteries, new cushions in cabin and cockpit, new SIMRAD NSS Evo 3 Nav System with autopilot w/9”touchscreen chart plotter on bulkhead, SIMRAD dome and SIMRAD wind speed and depth, rebuilt and restored overhead hatches in main cabin and V-berth, new aluminum 50 gallon fuel tank, new Raritan pressurized fresh water toilet with new 20 gallon holding tank, new Thurston/Quantum jib on Hood roller furler, new Thurston/Quantum canvas sail covers, Lewmar 44 2-speed self-tailing sheet winches, mast mounted halyard winches. U-shape galley, 3-burner propane stove w/ oven, refrigeration, hot/cold pressurized water, shore power connection. 120v outlets at nav station and galley, 30amp battery charger.
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)
Aft and center cockpit, ketch or cutter.
