This sleek Beneteau 51 aft cockpit sloop is in very nice condition and loaded with all the equipment you need to go cruising. She is laid out with four cabins-two forward and two aft each with adjourning head. Great for a big family or for chartering. The large and comfortable salon area is to port with the galley, refrigeration boxes and nav area to port. The engine is centered between with easy access. The generous beam allows all these areas to fit harmoniously and still give a big and comfortable cockpit area. The dodger and bimini make lounging in this space or conning from the dual steering stations-a dream. On deck she carries a 50lb Delta anchor with 200 ft 3/8 chain and a Tigress 12V windlass. She is a slooped rig tall mast with heavy 1X19 wire. The 125% genoa is furled on Profurl and handled by Lewmar 66 ST winches. The mainsail and genoa really power up this yacht and is fun to sail. There are dinghy davits, wind generator and solar panels.
Equipment: Perkins 4-236 fully serviced. New inverter/battery charger. Two 4D batteries provide 1800AH capacity-new. Separate start battery-new. Air conditioned. Raymarine ST-60 instruments. AutoNav autopilot. Furuno Navnet plotter with radar. Icom 802 SSB. New Tasco stove/oven. Frigoboat refrigeration/freezer. 10ft Mercury dinghy with 15Hp outboard. EPIRB and other safety gear.
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)
