Brian : I'm not disagreeing with anything Arvel wrote there. My point is that adding aero drag is beneficial much of the time on most conventional...
"Staysails that are 'overlapped' by A-sails don't add upwash, lift, etc." Maybe the answer is that they're adding drag, which increases the...
Precisely! I think you will find that the desirable operating range gets ever smaller as the flap deflection angle increases. Here's a plot of...
Maximum flap deflection on my Mach2 foils is less than half of that. I don't know for sure about more modern designs, but I seriously doubt if...
Here's a fairly old (but still good) description of the system that Moth class sailboats use to control the ride-height: Magic-Wands.pdf
Do you expect us all to go out & get these books? How about summarizing for us what these three approaches are.
Where did that idea come from? The lift at the root is usually the maximum.
Can we please get back to discussing hull shapes? Some of us really do think they can be important.
What's the meaning of subject #2? If you mean CFD calculations, both fluid compression and particle deflections are irrelevant.
Rod Mincher's blog (Earwigoagin) has a good article on the Suicide class: Earwigoagin: Search results for suicide
I believe that solid booms were legal but uncommon (possibly because of the measurement rules.) My dad had a Suicide (named Cyanide) with a solid...
Here's a newspaper photo from 1939. The overall quality isn't great, but it clearly shows a raised daggerboard. Suicide_Yellow Peril by Doug...
You don't have to read the book from front to back. Flipping through it, you should find plenty of interest. I get it though. You just don't want...
