I'd suggest you read a couple of books on boats which will explain the difference between a displacement hull (sailboat) and a planing one (speedboat), hence the reason why 50hp is too much.
These are my favourites :
The Annapolis Book of Seamanship
Chapman Piloting and Seamanship
Don Caseys Complete Illustrated sailboat Maintenance Manual (more for fixing stuff)
