Bazı teknelerle ilgili dergilerde ve web sayfalarında confort ratio, capsize ratio ve benzeri hesaplar çıkıyor.
Araştırdığımda ingiliz/amerikan ölçülerine göre formullere ve değerlendirmelere rastladım.
Acaba bu formüllerin ve değerlendirme kriterlerinin metrik olanını bilen var mı?
Displacement/Length ratio
The best measure of a boat's relative size: displacement compared to waterline length. An analytical ratio, not a dimension. Rough classifications:
Ultra light racer: 60-100
Very light racer: 100-150
Light cruiser/racer: 150-200
Light cruiser: 200-250
Average cruiser: 250-300
Hefty: cruiser 300-350
Very hefty cruiser: 350+
Sail area to displacement ratio
How much sail the boat carries for its size, a power-to-weight ratio. All else equal, high-powered boats are faster in light air, reef earlier, and can be more difficult to handle. Rough classifications:
10 - 13 under-canvassed
14 - 15 conservative
16 - 20 high-powered
20+ very high-powered
Comfort Ratio
Measure of the boat's up-and-down jumpiness due to waves. Uses displacement, LWL, LOA and Beam. Rough classifications:
>40 slow motion
25-40 moderate motion
<25 quick motion
Capsize Screening Factor
How likely a boat is to recover from a capsize, based on beam and displacement. A quick and dirty measure of offshore suitability. Down from 2 is considered increasingly quick to recover. Above 2 is increasingly likely to stay turtled.
Length-to-beam ratio
Beaminess (lower L/B) usually adds to initial stiffness and interior room, but also makes for a rougher ride and greater difficulty recovering from a capsize.
<3 relatively beamy
