How to calculate sail area to displacement

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 https://shieldsofarms.com

WebSail Area Displacement Ratio, where SADR = SA / (D/g) 2/3. The SADR is a measure of the power available to push the load (the displacement). Generally, the higher the value the faster the boat, provided the boat is stiff enough to handle the larger sail areas. Reference W … WebA semicircle cross section is assumed where Draft= BWL / 2 and CSA = (pi * Draft^2) / 2. If "Use minimum wetted surface" is not checked then CSA must be entered manually and BWL is used only to calculate "Length-to-Beam ratio"; the shape of the cross section is up to you! LB is always derived and cannot be input.
