Minimum Planing Speed

NoBozo · 09-09-2009, 03:07 PM

I think the faster a (planing) hull goes, the smaller the wake will be. This is particularly true of the Deep "V" hull which usually has a 24 degree deadrise. This hull will leave less and less wake the faster it goes because it continues to climb further out of the water on the "V" and lifting strakes, reducing wetted surface...allowing it to go even faster.

A flat bottom planing hull, such as a hydroplane, will plane off earlier and with much less effort, and leave less wake. NB

PS: The power to weight ratio probably has as MUCH to do with it as hull shape I think.
