Warbird,

Overall width may really help you here also.

It could be an idea to just remove the trapeze and make the boat wider and only hike off it.

If you are really after planing then have the luff hull take part of the planing. This will make the platform very rigid in its side to side attitude and allowing you to keep optimal planing angle better.

Again this assumes that you can get proper planing to work at all.
