2002 Bimare Javelin formula 18 High Tech In good overall condition and ready to sail. Just had two days of great solo sailing. Looking for a high performance 2 up Cat you can single-hand ? The F18HT is a little known rocket ship, weighing 130kg, its 50kg(110lbs) less than an F18. Its the faster boat in most conditions, with Portsmouth rating of 60.0 its very competitive in open regattas. It’s a simple boat, tall carbon rig, big main, big kite, clean layout. I can unload it, step the rig and go sailing by myself. Comes with two sets of sails. The first set has plenty of life left in them, but not so pretty. The second set, a newer reduced area main used only a few times, and an older kite in excellent condition. The hulls are solid, all the blades are in good condition, and the aluminum is pretty clean. The mast has never been broken, but has a few repairs. New: EVA decking; 9:1 Harken Carbo main sheet blocks; spin hoop and bag; shock cords; foot straps; spin halyard and other misc rigging. Comes with alloy tiller extension, trailer and beach wheels. Can deliver a reasonable distance for a fee. I have another F18HT, plus other boats, got to let this one go. you can find some vids on you tube, here are couple samples. https://youtu.be/84nIkIjJT3U?si=Md4kDH1FG845AB4Y https://youtu.be/TLykPe1jgmM?si=oASRJ88NUKxJPySR
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)
