That's a big wheel, and implies a large boat. Too large for Weston Farmer's "Irreducible" to be a satisfactory design. It only calls for a 9"X9" wheel. Weston Farmer (the Elder) was...

This is one objective of sanding, but not the only one. J.E. Gordon, in "The New Science of Strong Materials" relates an account of how inconsistent adhesive performance in glued...

I think that a flat bottomed boat would give the best chance of planing on small hp. It will give more lifting surface and less wetted area than a step sharpie and also weigh less. Planing...

Here in the land of politicians suborned by ADM, our regular gas is 10% ethanol, a hypothetically renewable fuel. I have a boat with a mid '80's vintage 40/35 hp. Mercury. Having...
