Planing hull clo coefficient
WebOct 1, 2024 · In the current hydrodynamic research relating to planing hulls, the stern flap and steps are generally considered to be two independent resistance reduction measures. Limited research has focused on the coupled effects of flaps and steps. Therefore, experimental and numerical simulation methods are carried out in this paper to explore … WebPlaning Hull Calculations (Crouch's Formula, English Units) Description: This boilerplate spreadsheet performs planing boat powering calculations using Crouch's formula (a planing boat power prediction method). Result graphs are automatically generated and show speed in knots versus brake horsepower required.

WebApr 12, 2024 · A value of 190 works well with classic Boston Whaler boats. Hulls with Whaler Drives may be more like 180. Long and narrower hulls with with flatter running surfaces may have a higher hull factor coefficient, perhaps 200 or higher. Actual measured values for power, weight, and speed can be used to compute a hull factor coefficient.
