Are you looking for a boat that is ready to sail on Carlyle Lake? Well, look no further than this 1982 S2 8.5. Disclaimer is a well-maintained example of the $2 8.5. Built in 1981 but technically a 1982 model, it has been stored on the hard every winter, has had bottom paint applied annually, and has always been sailed in fresh water. It has an extensive equipment list; the high points of which are listed below: Yanmar 1GM Diesel, martec feathering prop, wheel steering with integral teak cockpit table, cockpit cushions, Bimini, stern boarding ladder with extension, Icom radio, Lowrance chart plotter, 110 volt AC electrical system, Battery charger hood profurl furling; cockpit led, Whisker Pole, Life sling 2 Overboard rescue system, North Main, North 155 Genoa, North 110 Jib, Steel cradle, Full teak interior, portable AC, Porta Potty. This is a sound boat in good condition. As with any 40 year plus vessel, Disclaimer has its imperfections, but it has been sailed and maintained by a knowledgeable owner for the last 24 seasons. It is ready to sail away with a minimum of effort from a new owner. If you have any questions or would like an appointment please call 618-594-2461.
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)
