For rough water or wake jumping there are 3 things you want so the boat won't come apart or not end up spider cracked all over.
1 full length rails
2 deck brace
3 taped deck/hull joint

If you don't get all 3 in the hull you are looking at, be prepared to add them yourself.The bigger (longer) the hull the more flex it will have on the deck/hull joint and hull bottom,so the more critical it is to have it reinforced.A 20 pound 56"+ boat will destroy itself in an afternoon of wake jumping.
