TBDP - Help Manual

Here is a method to simulate a 3-point hydroplane design setup, using TBDP. Model a forward sponson, 3-pt hydro design by:

1) set tunnel height to 0.0 inches

2) sponson length to forward sponson length

3) aero AngleInc to the appropriate angle (degrees) to match the height of the sponson height at their trailing edge. (When calculating the AngleInc, use the Length from hull aft trailing edge to the forward sponson trailing edge).

Lift and drag components will be only approximate, but will be quite representative and very helpful in optimizing design.

[Note: TBDP is best applied to tunnel hull, power catamaran and modified vee hull designs, but is also used for performance analysis of 3-point hydros.]
