Look at the splash boards/top of transom, all aluminum and form fitting in the before pics of the Mako 222.
The Tsunami I really like. Do a bracket base for twins and with a single engine setup for my V. Not breaking any new ground here, it has already been done, very nicely I might add. HERMCO looks to do some fantastic work. On the HERMCO brackets - it looks to me that the bottom of the bracket doesn't swoop up at such a drastic angle as the Stainless Marine brackets do. Something I also took away from Big Shrimpin's build and Smoking Joe's. That and the V design would add additional bouyancy because it all happens below the waterline. I saw a picture on HERMCO's site that showed some thick core material and about 6 layers of biax, and that was only the inner skin. Heavy glass encapsulated wood frame I guess??
Jasoncoopercola- Your drawing nailed the design I had in mind perfectly and would be my second choice. Easier on the budget..
