Excellent Condition, clean, 100% serviceable, and minimal usage. The OPen Bic has blown a big breath of fresh air through our sailing world, close to the new-generation Bic concept, very fast and very simple. 100% open, self-bailing, rapid and responsive, with an up-to-date versatile rig, the O’Pen Bic offers kids a machine that delivers maximum fun while helping them learn the skills and reflexes to enjoy racing on current, high-performance equipment. Hundreds of sailing clubs around the world have opted for the O’Pen Bic , for a new, fun way of teaching sailing to appeal to youngsters attracted to new sail sports.
On the hull, the shaped daggerboard and rudderblade, and all deck equipment and fittings are worthy of the most modern dinghies: Ronstan Cunningham pulleys and Ronstan mainsheet ratchet block, Robline ropes…. The rig includes a fully-battened North 4,5m2 mono-film sail with mast pocket, similar to that of a windsurf board. Rigged on an epoxy mast, the sail has been designed with an open leech to give sailors maximum control and performance in windy conditions. New MSRP was $3,650 with entire kit and Dolly.(Asking much less.) Prefer pick-Up or free local delivery. Non-Local shipping is extra cost.
Equipment: Hull, Sail, Rigging, Daggerboard, Rudder, and Hand Dolly are all included with sale price. Also includes carrying bag for Rudder and Daggerboard.
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)
