My BWM hull is said to be a deep V (mabe on the shallower side of Deep) but I recon that my Hull has a maximum hull speed of about 42 knotts. She was getting very wobbly when only slightly trimmed out at this speed when conducting prop trials.

What I did notice though was that at 4000 rpm with different sized props I was getting quite a range of various speeds. But maxed out at WOT the top end was pretty much the same.

Hightower!

A "planing pad" should help you. People here say the planing pad should help you to get on plane, but we had a boat "hardhull" 21´. First we had a v8 inboard around 300hp.(50 knots), Then a outboard, johnson 225 on a bracket (53-55knots) and very wobbly. And after building a planing pad and no other chances we got 59-61 knots and no wobbling at all.

With a saw! Cut away and build a new bottom. It was a step like a stepped bottom to the planing pad. It was -94 and no pictures is aviable. I have some on the boat in my garage but it doesn´t help you. It was a friend of mine who did the work. Lenght around 120cm and wide around 15 cm. It was no problem to take sharp corners at all. Hmmmm I had to take a look in the garage after my photos.
