I punched through the launching pad and tagged the rock killing my speed. The boat went deep in the hole. As I came out the back side my front wall floated out the side of the boat as I sank into the pool. I blew out about half the seams and being in a race boat had no float bags or duct tape. Ended up borrowing enough tape to slow the leaks but had to hurry bend to bend on the lake and dump so as not to sink.
