Thanks for the reply!
That's why I think the hull extension is the best solution for me; just a lot more complicated.
I have limited space and equipment, so I need to make it with simple methods and tools.

I can make it in stages, such as making a simple, one piece transom first and then cutout the opening for the tub. But I'd have to glass the tub later- wet on dry.
To make it wet on wet, I'll have to make a more complicated mold, so I can do the layup at one time.

Right now I'm leaning towards making a one piece mold, about half the transom height, basically from the tub level down. It'll be more like a Euro Transom, where everything will be tied together.
Even the deck could be the integrated into the tub by extending it into the swim platform, if the heights work out.

Then I can make the bulkhead later, at whatever angle I want.
I could glass the bulkhead into the deck and sides, or make the bulkhead with an opening like a door or even wider, have the whole thing fold down, like a gate.

Some interesting possibilities!

Got some 1/2" MDF board and 1/4" Melamine panels, and 2x4s today, so after some grinding, I'll start playing with the layout.

Would be nice to cut some Formica faced 3/4" board and build a frame to hold the extension in place, but since I don't have a miter saw, I have to make the cuts by hand. The MDF board also doesn't have a smooth coating, so thinking of coating the mold insides with epoxy and then wax or wrapping the parts with packing tape.
Glassing is going to be the easy part.
