We can learn from these racers. This class was a hydro class. The need for safety cells resulted in a switch to a tunnel hull. The tunnel celled boat was much heavier compared to the hydro and they thought non competitive to the hydro. This is a video of the early celled tunnels in the same race as the hydro's. The newest celled tunnels have a much lower cell. There are different classes within the race. https://www.youtube.com/watch?v=JJTuMNsowiI |

The safety cell came about because of the class speed. Safety cells are required in the 100 mph classes I believe. The pro guys could comment on that more accurately. 750 and 1100 cc classes. |

Some T's in the video as well. https://www.youtube.com/watch?v=fVT-NqXgD4k |

I notice they are running studs on the power headband they look large. I'd like to see how they work the adaptor plate and steering bars with that setup. |

Rick (Dok) has a Yamaha 30hp that he has offered to let me use and test with next spring. I think that will be a good combo. I built this hull for a Mariner Magnum 40hp, but will try the 30 first. What engine sizes are you thinking of using? 25, 30, 40+?
