I'm with Mike on this I'm afraid - there are a lot of things which don't look quite usual. To add to Mike's list here are another three. These are just thoughts, based on very small pictures, others may see things differently!

- Looking at the sheer, I'm not sure how easy it's going to be to build to that shape. The sheer curve gets determined basically by the way the gunwhale stringer bends: you can't just draw any line you like and expect it to magically end up like that. It's a small diagram but the sheer seems to be much more curved in the bow than the stern, implying a twist in the gunwhale. Possible but not trivial.

- Looking at the rocker there hardly seems to be any, and it doesn't appear to differ between bow and stern, although that's very hard to see with no waterline. I think if you look at most successful designs of this type you'll see a bit more rocker in the bow than the stern.

- In a more subtle vein, looking at the bow and stern sections, the bow section appears sharper than the stern section for a longer distance from the knuckle. That together with the rocker looks to me like it might be a problem: it almost looks like the hull has a built in skeg at the front rather than the back.

The acid test is always to build it though - have fun!
