Re: [harryproa] Re: progress

G'day,

Feel free to post any logo ideas. At present there is no official
harry logo, so all ideas considered, especially the outside the square
ones.

How would a harry (say Solitarry) go against Crepes Wahou?

Solitarry is:

About 20% of the weight (800 kgs vs 4.2 tonnes)
30% the upwind sail area (50 vs 170 sq m)
40% of downwind sail area (100 vs 250 sq m) Solitarry's is a kite, so
a) it can sail deeper and b) it is in stronger air.
About 50% of the windage. (estimate)
About 30% of the water drag. (guess)
Bruce number 1.92 vs 2.03
Cost $50,000 vs $1-2,000,000
Ratio of possible problems 1:100

In theory, Solitarry has a pretty good chance. In practise, it would
be up against a legend sailing a state of the art boat with tens of
thousands of miles of experience, so would probably be hammered. As
you say, make it a cost based formula, and there would be no argument.

Also interesting would be to see how Blind Date went against the
cruisier Classe 50's such as Victorinox.

regards,

rob
