What these plots say to me is that it is very attractive to design a 300 kg hull (although I think 190 kg for the crew is a bit high). Because it appears that sailing a 300 kg hull light (180 kg) hardly increases the drag at all. Especially since the hull related drag at max makes up only 20 % of the total drag of a beach catamaran. So even if the 300 kg hull sailed light has 10 % more hull drag then it would only amount to 2% increase in drag over the whole drag of the boat. This is negligiable. Clearly sailing a light hull heavy is much more worse.

Thanks alot for the graphs Grob !




I'm willing to help you guys out in the way of beams etc, but as written earlier I'm not pulling this car and I'm not accepting any cumbersome publication methods.

I do think we got a great project going here, but some of you really do have to get that site up and running and one that is easily backupped and updated.

Why not just make a site with PDF files and have a download corner where the original Word documents are. A person can then download the word file, make the changes and submit the new Word file to be checked and converted to PDF. Simple, easily accessible and spam proof. I'm sure Paul Warren will make space on the formula16.org website. Now we only need someone to check and maintain this segment of the project. I'm already doing the picture and video gallery so count me out of this one. I'll be only a contributor nothing more.
