I'm finally firm on this desiscion
Come on Frog - thats a selection - not a decision.
I am fairly confident that one of the hulls you listed is presently not available in the US yet. (I cannot name the Manufacturer - only that it has three letter and starts with an M and ends in Z) but I would call them first if this is a serious contender (though likely @ $1k for bare hull I am not sure it is).
Easiest way I have found to fill holes you do not need is to NOT DRILL THEM. Measure twice cut once. Measure three times and drill once. If your not sure - dont drill it. The only holes you will need are at the transom for drive, rudder, pipe. You may open an intake or two but TAKE YOUR TIME !! IF you need plans - ask the manufacturer at the time of ordering.
I have to ask - whats a "Black widow kit" ??
Sounds like your on the right track though. SHould be a fun boat.
