Ok, I hope this question doesn't sound too dumb.. I just built a boat, and it didn't have the tag on the back so I didn't know what the weight capacity was. Its a 1969 14'; starcraft v hull. I was wondering if by filling the bottom of it under the floors if it would make it float better? I haven't had the boat in the water yet, as I am just finishing up with the final bits and pieces on it. I am just nervous that it may sit too low with everything I put in it... But cant figure out if adding foam inside the boat would have any effect on its performance with it being in the boat rather than floating in the water by itself?
