I am selling my 2001 Vanguard 15. The Vanguard 15 is a one-design fiberglass racing dinghy.
It is in fair/good condition (a couple gel coat scratches/repairs around the edge of the hull). The sails and rigging are in good condition. This boat is ready to sail once it’s rigged.
This boat is fast and planes in 12 knots of wind. It looks and sails like its smaller counterpart the Laser but this boat is designed to accommodate 2 people. It can also be sailed single-handed.
Features of the boat include: Molded gunwales that fit the shape of the sailor’s legs. Hiking straps. Recessed jib leads. Non-tapered mast. Molded kick-up rudder. Self-bailing cockpit. Main sail and jib.
Accessories include: Laser Performance sail bag. Travel and storage bag for the rudder and daggerboard. Spare tire
This is a beautiful boat aching to get out on the water and fly with the wind!
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)
