Therapy is a comfy lake cruiser. Perfectly large for a boat that you can still trailer. She was sailed 2-3x a week for 4 seasons, but I’m ready to move to a faster boat. Specifically a J24. Would be willing to trade for a good condition J24.
She has some scratches and I’m painting with Petit Ez Epoxy and Ez Decks. Price is currently discounted while I complete the paint job. If you purchase before I’m done painting I’ll include the paint. Also, painting is a good opportunity to change the name of the boat.
Equipment: Roller Furler, 2012 110 jib, 2018 155 Genoa, 2019 Footed Mainsail traditional battens, 2018 Symmetrical spinnaker, 1985 but like new! Some other old sails, good for backups or practice. New running lines, 2020 All lines internal and back to the cockpit. Yanmar 1gm10 inboard diesel, works great! 2 axel trailer with electric brakes. Bearings are great, tires new (2020), road worthy.
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)
Draft for shoal draft/wing keel version: 3.33’/1.01m
