Unusual Placing of Plate Hardware

Note the spacing of the plate pads from the rear edge (the outboard pads are further forward from the trailing edge than the inboard pads). What was the purpose of this?

Evidently this guy had some good ideas... (GN Champ).

Here I thought you had an engineering degree. Whats your best guess Bill?

And thats the only reason?

I can't speak for the amount of pressure it takes to move that plate.
I guess you were around when motorcross bikes first started moving the shocks forward on the swing arm.

The hull isn't known as a hard turner. Imagine it turns much better if the plate is turned down on the out side, but it slows the boat down. Now if you could lower the plate more on the outside ONLY when you plate it, it could have the same effect as setting the plate lower on the outside.
It might also have some effect at controlling chine walking as well.

Just a guess. But the outside back edge of the plate is definitely going to drop further than the center when its plated.

Seems it would help on a v-bottom as the outside edges don't have as much pressure on them as the inside edges, so the extra distance should help give you more down without affecting handling like it would on a flat. Just a guess though- what is the real reason GN7? I can see you smirking over the Internet!

I'm not smirking. I am just thinking that if you set the plate so it turns well, and it turns out the outside of the plate needs to be down, but it causes too much drag or sets the boat too much, but the setting the plate for speed takes away the turning, how would you handle it?

It could very easily be nothing more than a geometry thing to keep all the turnbuckles inline. But it will sure will move the outside of the plate more than the center when you plate it.
