Whale Tail / Hyrdrofoil plate design & questions - Laser 1750

CORRECTION: Boat is a BULLET 1750 (teach me for typing this up half pissed)

Happy new year to you lot!

I've made up a hydrofoil/whaletail plate for my little Bullet 1750 in an effort help keep the nose down at low speeds and take off a bit flatter. This boat's all weight in the ass and none up front, and although it has plenty of power to get up on the water, it would be nice to be able to cruise a little slower with the nose down (below about 25mph it's hopeless even with motor tucked right under)

So I made up this plate, which has made a big difference and drives great, but with the side effect of throwing up a wall of water behind the boat as you attempt to slow down again. The hull sits so low this could be a problem if you're not very careful and I don't want to sacrifice safety

Once above about 35mph this plate is well above the water and does nothing which is fine by me.

Does anyone have any ideas about changing the design to stop this tidal wave from trying to swamp the boat when slowing down? I was going to cut about 2" off the rear to see if it helped but I'm guessing here

Cheers!
