In 1996 the company was named Thoroughbred and the boat models were Velocity. Then he changed the company name to Velocity and later Initial Marine. When I have mine built in 1996, he offered an option for a race layup, those boats kept the Thoroughbred name, not Velocity. I stripped the Thoroughbred off mine and replaced it with Velocity.
The difference in speeds is merely how well the bottom was done on the boat. Take the boat and have the bottom blue printed.
