“The starting point when dimensioning the rig is to calculate the

good design angle. This corresponds to a reasonably high wind strength
with the sails still generating high loads and the boat making good
speed through the water. Letting the boat heel over more....in reality
means a slower boat owing to increased resistance, with a
correspondingly smaller dynamic force.”

Funny, you picked almost the exact same words I would have

"Letting the boat heel over more....in reality means a slower boat owing

They're talking about stressing the rig, not best sailing efficiency.


Note the _more_!!!! Now, who's talking efficiency? We were talking about
powered up! (I now accept that you may have no idea what that means).
Now define effciency for us so we can be sure that we are going to speak
the same language if you want to discuss efficiency.
