Sorry for your loss.
Sounds like the boat was fast, maybe to fast. You don't mention a lenght so I'll guess 17, 18, 19. 400 lb lay up is pretty light. Tunnel, Semi-Tunnel, air catcher. At those speeds catching air is a given. Sounds like a true accident. BTW, the pearl white Eddie Hill boat was called "The Texan", It also had a black texas star on the deck.
