1981 Endeavour 37 for sale. Perkins 4.108 runs good. New 3 blade prop and canvas glass this year. Jotun Paint job. Have main sail, and a few different hank on jibs. Great cruising/live aboard boat with lots of room inside and very clean. A lot of hard work, custom work, has been done. Electrical and plumbing primarily is next. But mast has all new wiring run to new VHF antenna, mast top lights and Garmin windvane. Also new Garmin transducer. Interior was completely torn apart since lots of mold was hiding behind all the aged headliner/wood mix. Sanded everything and gelcoated fresh. Making her clean and easy to wipe down and NO rotted old moldy boat smell. Re bedded everything making her leak free. New interior cushions and v berth bed. She has been our summer home for a few years. Slip is available for additional price and transferable in a prime and great location. Have stands to go with it plus many many other little additions and supplies.
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)
Rig dimensions for yawl rig.
