I haven't spent enough time above about 6kts to have had the opportunity to study high speed boating personallly. But I think the basics of Physics must apply to much of this question (except the magic of hydrodynamics / aerodynamics which are usually totally counter-intuitive!)Johnca said:Thank you for the info.
Now I am going to visit dealerships with boat equip with small skeg and mesure the hight, length and the position (middle, forward or backward). Than with different boat builders there will be a ''tipic'' place for the skeg.
I think personnaly that the skeg should be in the middle of the 19 footer boat?? Just in front of the pylon were the tow is attach now. I will make sure that the tow is lower as possible just to clear the outboard motor.
For your info the boat nose stay low during skiing. I am not worried about boat flip over the width is 96 inches.
For me it is interesting to use physics to solve daily problem and experiment.
If you are in a position to make changes to your boat (re-position the skeg after trials) then you have a good chance of getting a good final solution. I might suggest that a position behind the centre may be better - but look at existing designs first. Too far forward may compromise low speed turning.
It sounds like an interesting project.
