14 lis 2006 · One small question: how is the hull displacement calculated? You need to know waterline length, waterline beam, and body draught amidships (just body, not total draught under the keel). Then you need the "Block coefficient" which may vary a lot depending on hull forms.
8 lis 2013 · To get a real displacement you need a center of masses calculation, so you know how much hull you'll need so she floats where you'd like her to float. Post a picture or sketch of your proposed hull (all three views).
What we have here is our Interactive Sailboat Design Ratio Calculator, which does all the calculations for you instantly and avoids all the pitfalls described above. The pic below is where you would enter the dimensional data on the downloaded Design Ratio Calculator:
27 kwi 2018 · The formula is as easy as ABC: Displacement (pounds) divided by 2.240 and then divided by the length of the waterline in feet cubed multiplied by 0,01. There are numerous online DLR-calculators available on the net, just do a quick research in the search engine of your choice.
The CSF compares beam with displacement since excess beam contributes to capsize and heavy displacement reduces capsize vulnerability. The boat is better suited for ocean passages (vs coastal cruising) if the result of the calculation is 2.0 or less. The lower the better. CSF = Beam/Disp (cubic ft)^.333.
