Eric, thanks for the clarification. One point I don't quite get is how the heavy/slower boat will be at disadvantage with a more efficient rig...
Eric, thanks for the info. I'm well aware of your excellent Design Ratios text; as a matter of fact, I re-read it yesterday before posting this...
OK, might have been generalizing a bit... Apologies. Still, look at this VPLP 2013 design for Lagoon Catamarans. Close to 45% of the SA in the...
point taken, I've been studying catamaran designs lately and the most recent designs I could put my hands on have the mast way aft, with a high...
Power is a function of efficiency. What if you have the choice between a small powerful rig and a bigger, not-more-powerful-than-the-other rig...
Or to make it even more real-world: With a more efficient rig, you could have the same hull, going the same boat speed but have a smaller rig:...
It has to to with available power. The amount of wind available at any given time is finite; The quest is how to use it the best. If you could...
Is there a power-to-weigth ratio that would include the rig efficiency into the calculation? Perhaps through AR of the main? My understanding is...
Doug, i wonder how they derive the advantage of lift vs heeling moment... Thinking out loud here: if the force created by the lift is decomposed...
canting keel angle Look at the pic I joined: In blue, keel with horizontal axis, then the same keel rotated out 45°. See in the right viewport,...
depending what the surface under it is, you can roll silica-thickened gelcoat. Mix silica into the gelcoat before activating to a mayo...
