The Raider sailboat looks a bit like a cross between the Vanguard Vector and LDC’s RS300 singlehander. Its greater length and beam make occupancy by more than one person far more comfortable, and not too many skiffs have built-in drink coolers Designed by John Drawe, the Raider was conceived as a high performance skiff with easy handling. The builder comments: “We wanted to keep it simple and affordable in construction and easy to sail for all sailors to enjoy the sport regardless of skill level. The Raider is easily controlled and has strong windward performance in a breeze. Racing straps, 0 carbon fiber mast very easy to install in few minutes and take off for travel. Fully functional trailer included and ready to hit a route. Raider 16 built in Vero Beach by Johannsen Boat Works Easy set up with 2 piece lightweight carbon fiber mast. 120 sq. feet reinforced sail. Competitive racing boat or easy going day sailor. Boat weight 200 lbs. 400 lb. max capacity crew. Garage stored.
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)
