F104

Now I've managed to upload the original photo's which are scanned from a French sailing mag

Voiles et voilers

here are some more facts and figures between the Cirrus Evolution, Spitfire, Hobie FX One and Mattia S Sport.
They don't appear to be the cheapest or lightest of Cats but this thread ISN'T meant as a means to start an argument about us verses them but to make people aware that we as an International Class have a lot to do to gain new F16 sailors.

Did you mean to link to this?

IMHO Cirrus is a very underrated builder.
Checkout the B1 (their latest F18 design) which is as good as Hobie or Nacra (if not better) but not sailed very much outside of France and Belgium.

I dont think we will every be able to rest on promoting.. Part of keeping a class alive..

Nice looking cat, some good ideas on there apart from the rudders, bad shape. Daggerboards are too long also.

Viper is a F104 isn't it?

Darryn

Not in Current trim; It's too light / too much sail etc.

Hey guys...just stumbled onto this thread a little late...scooby, I was wondering what's bad about the shape of the rudders in the Cirrus Evo shape shown in the picture above?

I'm asking because I often sail in the local shallow mud pit and am trying to learn techniques to make foils which work as well as possible with shallow draft...and that shape would seem attractive to my inexperienced eye. Not the daggers, though, which seem perfect for oil drilling.

Also, do people prefer the lighter moments on those foils with the pintles roughly in line with the quarter-chord? Or are more forward pivots, encouraging better trim steering, preferred? (Yes, these questions are being asked by a reforming dinghbat...)

Morro Bay?

Gee, how'd you guess?

Seeing you asked the question I guess it would depend on wind strength. My current F16 rudders are in cassettes and are canted forward but their surface area is a lot smaller than my original F16 rudders which weren't canted forward. During normal sailing conditions I think only a very experienced Cat sailor would notice the difference but when it's either light winds or heavy winds then the difference in surface area and cant under the transome becomes more apparent to us mere mortals <img src=
