Agreed ;) but then the Thistles have a large & enthusiastic fan club. The
issue here is that light winds are very common on inland lakes and in some
coastal areas, so if for some reason one finds oneself living in such an area,
the Thistle is a good choice.



well, of course, for different windspeeds, different boats would win.

but, i would bet that if you set a windward/leeward course somewhere
with generally breezy conditions, and ran a contest that lasted, say,
several months - a formula windsurfer would win the overall prize for
fastest time around the course. i doubt that any skiffs, cats, a.c. boats,
or anything else would be as fast.

Well after looking around a bit more, it looks like windsurfer performance has
improved but as I said, so has monohulls. IACC boats VMG is pretty impressive,
so is the F40 cats and the C-cats. It would be an interesting trial.

One thing is for sure, to get a monohull with anything approaching this
performance, you have to spend a LOT more money.

I saw an open race last year where an 18-footer skiff, a canting keel Schock
40, and S&S '87 (the America's Cup cat) were in the same race. At different
times any of the three above were ahead and showing better speed than the
others, but overall the big cat won.



somehow, the prize for fastest time seems more desireable than one
for a particular wind range - to me at least.

But what you're saying is 'fastest time within a particular wind range.' Why
not give the other guy a chance to pick his favorite conditions, it's only
fair.





Personally, I haven't done any windsurfing for a few years, if the gear
has improved that much maybe I should give it another try.


with respect to windward/leeward performance in moderate windspeeds, the
gear has improved quite considerably in the last few years - i would say
the new gear is revolutionary. i also race dinghys and keelboats, and i
so i would say my opinion is an informed one. in light winds, say under
8kts, the performance gain isn't so big - 10 year old boards still win
in these conditions.

Personally, I'd like to see some new boat classes that incorporate some of the
same advances. Most popular classes are ~40 year old designs.

Dear Dumb-Ass,

The question was for "production" mono hulls, not experimental

Possibly then it is not the wisest decision (made many years ago) to
have only Thistle (and no other boats) as the Primary Yardstick in the
American Portsmouth Yardstick Scheme. This can give skewing problems
because of the biassed characteristics of its performance.

RYA Portsmouth Yardstick Scheme (on which Dixie was based in 1961) uses
several Primary Yardstick classes so making it more a level "playing
field" in comparing classes' performances.

These include single-handed and two handed, una rigged, two sail and
three sail (with conventional and asymetric spis), modern and older
designs.

What is the fastest mono-hull (non-sailboard)on a windward leeward or
triangle course these days?

I estimate: 505, Intl 14 GP, 49er, 18ft skiff are contenders.
Since they all plane up wind, waterline is less of an issue so I would
guess larger craft like an E scow, and A scow are in this class.

In light winds (under maybe 6 or 7 knots) AC type boats (long, narrow
keel yacht) are probabely fastest. A little more wind and i would
consider racing skiffs. Even more (12 knots and up) and Formula
Windsurfing gear has chances. But ultimately fastest are probabely big
(semi)planing racing yachts like the Open 60s or even bigger beasts.
Wasn't there a thread about a 150ft racing monohull shattering some
record a while back? Of course these boats aren't readily available to
most of us...

i agree with the a.c. boats, but open 60's and similar boats
aren't designed for upwind work. neither was mari cha - the boat
that beat the transatlantic record recently.

The problem with IACC boats is that they are designed strictly for windward
& leeward VMG, and furthermore are highly optimized for winds between approx
5 to 15 knots. They don't plane and could not be made to plane, but they do
have long waterlines & tricky hull designs so they can get up & downwind
pretty fast. But they aren't drag racers, their top speed is low by even
planing dinghy standards.

The Open 60s are the opposite, designed to scoot downwind (or at least on
fairly deep reaches). Around a closed course or upwind, they are not slow
but not in the running for fastest IMHO.

Mari-Cha 4 (the 140'+ new record breaking monohull, a ketch no less) has the
same design issues, but is enough bigger (LWL approaching twice the IACC
boats) & more extreme that she would have to be a contender any place she
could fit on the course. Supposedly this boat can go 2X true wind speed
under a wide variety of conditions.... a chop isn't going to slow her down
much!

Besides if a windsurfer was on the same race course with any of these boats,
all the other skipper would have to do is blanket him ;)

depending on what boats they race there, you might need more than
10 kts - 12 would be safer.

But that's boring! 17-20 kts is the sweet spot for my taste.

I'm pretty sure I can't plane my Formula stuff in 10-12 kts. (Of course,
I'm by far the worst Formula "racer" around...)

Oh, the speculation. Can we agree on some general principals? The
longer the course, the better shot a larger boat has. (There is a
reason that the 251' James Baines circumnavigated in 160 days, and her
record stood for 131 years.) The flatter the course the greater the
advantage to most windsurfers. The steadier the wind the better the
chance a windsurfer has. The lighter the wind the greater the benefit
of extremely efficient designs, like the AC class boats and FW boards.
The heavier the wind the better the more stable designs perform,
designs like offshre multihulls and massive monohulls.

Finally, the smaller my wallet gets the more I like FW boards for
their comparatively cheap thrill!

Good point! And could you imagine being dead in the water with a 140 ft
boat bearing down on you?
