WebNow when the weight of this displaced water is calculated we take the product of the volume of the water and the density of the water. ... FWA (in mm) = Displacement/ 4x ( (water plane area x density of water) / 100) Or FWA = Displacement / ( 4 x TPC) ... As a ship sails the seas the SW density is assumed to be constant at 1.025 gms/cc, ... WebSail area in sq. ft. Displacement in lbs. SA/D =. Bruce no. =. Caution & Warning.... Oh the ways we can deceive. As with the D/L ratio, the displacement figure used must reflect the real-world weight of the boat in the water. Where you're most likely to be led astray is …

WebForces on a moving sailboat. (a) Sail and keel produce horizontal “lift” forces due to pressure differences from different wind and water speeds, respectively, on opposite surfaces. (b) The vector sum of lift forces from sail and keel forces determines the boat’s direction of motion (assuming there’s no rudder). WebAs a result, the Displacement Length Factor (DLF) has been decreased for heavy boats, and the Sail Area Displacement Factor (SaDF) has been decreased for boats that a\re low on sail area. Taken together, these changes slow the ratings of typical Vintage and Classic boats by 2-3 sec/mi. the bang candy company nashville

Web17 mrt. 2011 · Calculating the SA/D Ratio. Having found a boat’s sail area, you next need to calculate its displacement in cubic feet (DCF) in order to ultimately find its SA/D ratio. … http://www.kastenmarine.com/_pdf/sail_area_ratios.pdf The Sail Area-Displacement ratio (SA/D) is a calculation used to express how much sail a boat carries relative to its weight. In the first equation, the denominator in pounds is divided by 64 to convert it to cubic feet (because 1 cubic foot of salt water weights 64 pounds). The denominator is taken to the 2/3 power to make the entire metric unit-less (without this, the denominator is in cubic feet, and the numer… The Sail Area-Displacement ratio (SA/D) is a calculation used to express how much sail a boat carries relative to its weight.
