Default IACC Boat speed at 30 degrees heel?

... Better yet go back to the classic literature and look at the tests
of the Gimcrack. She was fastest at 30 degrees and was no faster at 35
degrees. That's still a correct rule of thumb for most fast cruiser
racers today.



Not in my experience. Most boats like about 12 degrees of heel. The
Soling (a relatively narrow boat) sailors I know say their boats like
18.



I guess you would not have overtaken the race leader -look at this:

Great pics. But again.. a special case. Those boats are more like scows.
Besides, for publicity shots they like to heel the boats 'way over. And
the boat in the top pic is certainly not heeling at any great angle. I
guess you have to be *very* selective in choosing examples that support
your contention?

No, these boats are faster at 30 degrees of heel when beating as I keep
saying. Are your seriously suggesting you are a better racer than
Thiercelin who talk about being at a permanent 40 degree heel?

You are dead wrong on this one -admit it.

Key- 'these boats'

You keep picking expamles of extreme type and saying this is how normal
boats sail.

Nope, so far you have provided some interesting pictures and some
exceptional examples, but for most boats that is far too much heel for
best performance. The fact that you *think* you are proving something is
really kind of amusing.

So according to you the books I quoted on naval architecture are wrong?
Oh boy.

I wonder why Hood talk about sail design for Italy on the basis of an
IACC 30 degree heel? They must be wron according to Doug too! But,
didn't Prada win the LV?

You are sooooooooo busted.

Nav,

If you go back and read the opening paragraph on Hood's design goal of
sails, you have "BUSTED YOURSELF!"

They state the goal of design is to; "mininmize drag and heel"

My friend, I do believe you are beating yourself to death trying to get
at Doug. Give it up.

Nav,

Really!! You're not being fair calling those "Solo around the world"
boats mono's. Their beams are so wide and their draft so shallow that
they are Cats built in one piece and designed to sail with more than
half the hull flying.

They were just about as bad as the Kiwi POS used for the cup defense.

Their failure rate in that last so called race wound up being for
survival and not for speed!

their cedar bucket.

It was very sad indeed. To have banked their defense so heavily on
lighter winds was not a good call.
