Re: 'Big' question...
Well I'm a BOB (big 'ol boy) myself at 265 lbs., so I advise to go cautiously. Clean it out first before you put your weight on the inside of the hull, if it looks iffy lay some planking inside that you can walk/stand/crouch on instead of putting your weight on the hull itself. Glass boats are deceptive...they can look solid as a rock but why take a chance going though the hull? Recently recovered from "finding" a weak 2X6 in a friend's backyard deck...not fun, my right knee is still a bit sore and it's been at least a month. So check it out before you jump in there.
