I sent an email to Bob to see if I could get an update on how his Laker turned out. His website mentioned he was going to try a few things to improve on it, but I couldn't find any updates posted anywhere.
FWIW: This particular hull, while not designed for any known racing class, is modeled after one of his other slightly smaller racing boat designs, the Laker SC12. When it's up on plane, it's only riding on tiny sections at the back of the pads, so about 98% of the hull is out of the water. That and the motor lower unit is all that will be in the water when running at speed. There's not much of a wetted area of the boat left for the water to drag on. The hull between the sponsons is shaped like a wing and creates a cushion to help "float" the hull. Needless to say, Having a good working, and fast responding, trim setup is very important on a boat like this. Driving it carelessly or unattentively can easily lead to a blowover. I've watched enough different tunnel hull videos on Youtube to figure that out at least.
