sounds like your set. The boat should work and the bow should work.

IMO though I would try to find a recurve (45-60lb)or a compound (if you like them better) with at draw weight around 45-40lbsat a pawn shop or garage sale to use. 1) If your compound is over 45lbs you're gona be digging your arrows out of the mud and stumps most of the time. 2)Tokeep your hunting bow from getting messed up, bowfishing is a nasty sport that is rough on equipment. 3) Your sights on you bow might or might not get in the way 4) I'm not sure what kind of rest you have on your bow, but bowfishing arrows are substantially heavier that regular arrows and some rests cannot support them.

These are just my thoughts. I'm still trying to get this all figured out myself. Good luck!!
