Matt, That looks sweet!
If you really got 6 mph out of that plate, I'd like to see some close up pics.
I think I'm going to put in full length engine stringers, and run some outer stringers to hold up a floor that will run just about where the dash is.
I'm afraid the weight I am adding will slow the boat down, so anything I can do without blowers or turbos will be welcomed ideas.
Thanks, Len
