I am pretty sure that boat is 31 1/2 feet long from farthest transom point to bow tip. If so, it would not be eligible for Pro Stock V, where the maximum allowed length is 30 feet from transom to bow tip. Somebody needs to double check.
It would be eligible for Super Vee Extreme, where the maximum hull length transom to bow tip is 32 feet. That is the class it ran in before.
