I have a boat from around 1970, it has a 65hp mercury engine. The problem is that when I am <br />out on the lake going full speed I hit some wake and when the hull comes down it smacks<br />the water very hard. Once I hit the water pretty hard and it cracked the hull. I repaired it with<br />fiberglass putty and the fiberglass patch stuff but I don't want it to happen again so what <br />could I do to be able to hit waves at full speed without destroying the hull.<br /><br />P.S. I would rather do it myself so I could save money.
