(Would this also explain the whole pelican-striker discussion we had earlier?

Can't wait to see how she runs.
If it lives up to the promise, I'll be looking for put one on my boat...get lots of light wind events here in SoCal and I have a hard time staying with I20's upwind (better boards & more sail area...unless..!)
I love the fact it is completely within the class rules and has the potential to turn the competition upside-down! Very clever of them Mitch & his team...a true innovator if ever these was one.
This is why we need multi's in the games! Without this level of development focus, these concepts would rarely get off the drawing board.

Quite surprised that everyone has not gone this route.
Be interesting to see how much wind they can carry it up wind.
And at what point loosing area kills them down wind.
It is a risk for them, I know they changed the minimum wind rule for the Ollies this time, but not sure how low they will race in.
I assume it still passes the 75% girth rule. It looks like it does.
Good thinking batman!

I can carry my latest Grant Piggot kite up wind, I can tack it wire to wire as well, but I cannot carry it high enough to pay (I think); it's just feckin scary when the wind pipes up a knot and I have to bear off 50 degrees before I go swimming. It's funny in a scary kinda way!!!!

Tried and tested with an old T spi <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" /> But then there is no way out of the head-up single handed; Coming in off the wire and dropping upwind will get messy!!!!

A quick measurement on the picture suggest a girth much closer to 50% I seem to recall that the Tornado class rules actually do not contain a 75% girth rule as the other classes know it. Someone has to check this but I remember the Tornado class only setting max lengths on the foot leech and luff of the spinnaker sail and limit area and shape that way. Actually the hooter is a rather old racing sail. The ORMA tris used to have one as far back as in the 80's/early 90's. It is just that cats class rules disallowed such sails by rulings like the girth rule. Wouter
