If you read the Marine Technology article, you realize that induced drag far outweighs profile drag, even in fairly fast boats. That's why the...
At Steve's request I've been sorting through a lot of ancient family pictures and papers for American C class history in the late 1960s to early...
Since water is 800 times as dense as air, the drag of an object in water will be 800 times as great as the same object in water. Minimizing...

This is what we use on a 1/4 scale crackerbox model to make a seriously ill handling planing hull turn. That setup is for right turns, but a fin...
These guys have been building ships with non fossil fuel propulsion a long time. This year marks the 60th anniversary of the launch of their...
I did some quick research on foil sections as they apply to surface piercing propellers. It discussed supercavitating as well as ventilated flow...
