Do you mind if it gets muddy, bloody, and slimey? 47# is heavy enough poundage, but get rid of all the gizmos. Either shoot off the shelf, or get a bowfishing rest. No sights - they get in the way. Get no-gluvs instead of a release. Get a very good job so you can buy a boat, a bigger boat, a generator, a bigger boat, a bowfishing bow, etc.
