That's good for Mike , it's mean is theory is not wrong...
So maybe that's what he needs to do with his... bring the cut further back to the board!

The board turned out great decrepit. Have you had much time on it yet?

The nose on the Angulo is pretty Funky!!!

Thanks Mr love,
Yes have had a fair bit of time on it, into the 2nd mod now. The first mod was to change the way the rail chamfer at the nose blended into the cutouts at the back.
Initially the board was extremely slow to get on the plane, and not that quick once on it. Bugs (Phil Smith), advised that the blending transition would direct water into the cutouts, causing big drag. So I routed out the blend so it's now a sudden step between front chamfer and rear cutout. Has made a big difference. Now gets on the plane much easier, and goes faster, got a 35 the other day.
The other problem was pointed out by slowy when he first saw it. The height of the rear foot above the water line, my idea was to gain leverage over the rig, and this does work, I can raise the boom about 5cm higher on this board. However, the pivot point for the board wanting to rail up due to fin lift is at the water line, so the higher the feet the more they want to assist the fin in rolling the board over, means the sailor has to use ankle muscles to control trim. At speed over chop reaction times are too slow to do this effectively, and it's a big strain on the body. My shin was saw for about a week after an hour or so.
So it's in the shed at the moment where I'm digging holes in the rails, so my feet can get closer to the water line.
Matt also suggested the cutouts may not be deep enough, I'll borrow Elmo's helmet cam one day and try and analyse the wake, may lead to a 3rd mod.

Well it was only just 35 on trackpoints, doppler said 34.9 or something.
Just afterwards I had a go on a similar sized AB speed board with same sail and fin, and got another half a knot, but it was much more comfortable, due to the lower foot position.

Wow

That has to be about the ugliest range of boards I've ever seen!

YEP!!!!!!!!!!!!!!!!!!!!!!!!!!!

I was interested by the idea of longer water line length giving benefits..... where have I heard that before......
