Upright Resistance of Sailing Yacht Hull Forms

摘要

The Delft Systematic Yacht Hull Form Series has been extended with six light displacement models in view of modern trends in yacht design. Because of the higher speed potential of the light displacement yachts the existing polynomial expression for the upright resistance, as used for velocity predictions should now include a speed range exceeding Fn = 0.45, which corresponds to the speed limit of the original series. In the report a new regression model is given which covers a speed range up to Fn = 0.60.
