Hm....Just one on the left
I agree Terry. For heat racing the further back and the wider apart the better. For record trial and perfect water the single shoe or sponson works great. I even used a deep vee transom on a couple of riggers that work great for record trials, but for heat racing you will be sorry when you hit the rough stuff if you don't have the training wheels.I think having them on the outside makes the hull more stable in the "marbles", bigger wheelie bar back there...

Do you remeber the "Raptors" in the early to mid 90's? We took the front sponsons way wide with shallow rears under the hull without a shoe. Those boats could put down some oval times, and won several E & F 1/3 nats trophies. The water condition was rarely an issue. Even the F single engine could run at full speed with twins. With much effort and Marty's help we found speed by going deeper with the rears. Maybe a shoe was the way to go.I agree Terry. For heat racing the further back and the wider apart the better.

Hi John,
I think if the foot print is taken to EXTREME widths on the front of the boat,we may find rear sponsons are not always needed.

I agree they are not always needed. So long as the boat rides predictably without rears the boat can only go faster without those things hanging on the back of the boat. Especially if they touch the water at speed. They can be like brakes.I agree Terry. For heat racing the further back and the wider apart the better.

Let me think why we would want to use them.......... Reason one........They are used as wheely bars to make the boat stable. Much like brakes when they hit the water. Reason two.............As the primary riding surface having the fronts dance lightly above the water. Three.........They can form an air dam for ground effects when we use little or no recurve on the hull bottom. Reason four........They can be floatation on skinny hulls so the transom doesn't sink when the boat stops. Four.......They can be training wheels so when a front sponson bounces up, the opposite rear sponson trips it back in place. Five..........left rear deeper than right rear to hold right sponson to the water in a turn. Six.........right sponson deeper than left to compensate for torque roll. Seven.........the original; keeps the transom up in the turns and they fly out of the water in the straightaway for reduced drag. Eight........Center shoe to aerate the prop at slow speed and help on the launch. Nine...........keeps the boat from getting too much of a positive angle of attack when you let off the throttle at high speed so the boat doesn't blow off the water. Sounds like there is merit to some of those reasons, so it looks like a lot of experimenting before punching the ticket on the new boat.
Yeah no more waiting, the letters now actually pop up on the screen as fast as he can type them. :lol: :lol: :lol:
She was busy doing the yearly Christmas cooking. I have a computer that actually does not time out before I'm done typing!!!!!!I though Mary was out of town!
