Interesting spreadsheet, thanks very much! Can you give me pointers to the paper(s) or book(s) that describe the deGroot method?...
Re: dynamically unstable: that's actually a very good thing in fighter aircraft. Stable aircraft have aerodynamic forces that force the aircraft...
Perry, this is a good list of beautiful boats. Thanks for sharing!
Delusions held by one person: insanity. Delusions held by many people: religion. Arguing with the insane: priceless!
35 days, 4 hours, 8 minutes, but that's not a complete Atlantic crossing, only from the Canaries to the West Indies (Guadaloupe). This is two to...
Well, its that its ugly with an **intended** purpose, but there is no value in that purpose. Really: get bids from a dozen real yacht builders,...
I say this all the time so don't take it personally: there should be an absolute minimum of straight lines and flat surfaces on a boat. You don't...

Several ideas I like: the ergonomics seem good. But the boxy shape kills it. Look at any decently designed car, and you'll see ZERO straight...
I know someone who has built surf skis out of that cheap pink foam he bought from Walmart for a total of something like $20. One layer of glass on...
I know someone well who has started three times, finished once. As time goes on, he gets more careful about weight, not less. The boat he's raced...
