Actually the polars for my boat
show 6.5 knots at 35 degrees, but owners do better with the newer sails
of course, claiming hull speed even closer to the wind



What a crock! Are these the super secret polars!!! Sure, booby, they
do hull speed at 30 degrees true!

Please show us these polars!


I found this one for you:
http://www.cncyachts.com/99owners/misc/polar.pdf

Its the C&C 99 polar, for the deep fin model. This seems to be your
favorite racer; its rated at about 105. An impressive boat indeed - why
didn't you get one?

While the polar does indicate it can point up to 35 degrees true in a
breeze, the speed is falling so fast that VMG is no better than at 45
degrees. Heel will be increase, leeway goes up, comfort goes down.
Some novices might think its exciting. Very handy in a race, but not of
much use otherwise. Notice also that in lighter air, the dropoff starts
earlier. In 10 knots the optimum may be around 46, but she would only
sacrifice a few percent footing off to 50 degrees.

So Booby, please show us all those cruising boats that do better at 35
degrees true.
