Not the same as speed. But as speed doubles resistance of the hull quadruples. There is for sure a relation.
What do you mean?
No. The hull will be deeper in the water but as the hull is more or less round the shape does not change much. One hull more deep is more...
The underwater shape of the hull will not change much as the hull is more or less round. For sure the Tornado hull at the last part.
The problem is about a catamaran. The hull is very slender so form resistance will not increase against both hulls in the water.
Another question than. Is the answer correct? I hope somebody knows more about this subject.
The resistance is proportional to the wetted surface and increases quadratic with speed. Weight is cubic. So the full weight on one hull gives...
Can anybody tell me what is the difference in hull resistance (speed) sailing on one hull of a catamaran (for example a Tornado) instead of on...
