Gee, Taco...you don't give us much to go on. A boating course SHOULD be in
your future before you hurt yourself. The hull, provided it doesn't have holes
or cracks below the waterline should float, however any through hull fittings
for a bait pump or engine cooling (is it an inboard engine, an inboard/outboard
engine or an outboard engine?) etc. could sink you. You should talk to other
(more experienced) boaters in your area.
Best wishes
