Schock Wavelength 24, 1984 sailboat for sale Racing sailboat has Quantum sails: custom fitted mylar+Kevlar 155% genoa (excellent, cost about $2000), 130% genoa (fair), mylar+carbon fiber 100% genoa (excellent), mylar+kevlar main (good), several spinnakers (varied condition), Harkin roller furler for genoa (excellent, cost about $2000), two recently installed Lewmar genoa self-tailing winches (excellent, cost about $1200) for genoa sheets, TickTack Race Master connects wirelessly to Micronet thru-hull combo paddle wheel speed and depth sensor unit (excellent, cost $1400) contains flux-gate compass which is accurate to 1 degree and solar powered. RayMarine Tiller Pilot autopilot (like new, cost $390). Boat has “rod” rigging which is more costly than standard stainless cables. Has air pressure flushed PortaPotti mounted to floor with privacy curtain. No kitchen stuff. Sleeps 2. LED lights all-around. Has Yamaha long shaft, two stroke, two cylinder outboard which pull starts easily and is quieter and smoother than a small Honda outboard. Motor turns full circle. Has only Forward and Neutral gears.
Bottom needs sanding, small blister fixes, and repaint with Interlux VC17. Also needs weathered teak companion-way strips replaced soon. Otherwise it is ready to race competitively with a PHRF of 168. Looks fast and is fast. Similar weight (2500 lbs), dimensions, draft (4.5 feet), sail area, and PHRF (168) to a J-24 (162) but more comfortable, easier to use, and safer than the usual J-24.
Twin axle trailer with surge brakes on two front wheels. Five tires less than 1 year old. Double tongue extension reaches farther down launch ramp than most. Ladder and winch mount post. Small winch. Trailer is ugly but road worthy.
Firm price of $8000 as is. Just the priced removable items above, which do not include the hull, rigging, trailer or outboard motor, add up to $2000 + $2000 + $1200 + $1400 + $390 = almost $7000.
The boat is priced for quick sale. Will consider trade for 30+ foot boat.
Boat is on trailer at Columbia Sailing Club on Lake Murray close to Columbia, S. Carolina, USA for maintenance.

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 √LWLA 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)
In 2005, the WAVELENGTH 24 was brought back into production.
