Default Fantastic Sailing again!

How many sq. feet, Jeff???? You might want to check that again. You're
a BIT off!


Sorry, 322 sq feet. Still, its only 43% of the 742 feet on the Nonsuch.
Sail Area = Horsepower; there's pretty simple physics here. With 230%
more power, the Nonsuch easily overcomes its weight disadvantage (17,000
vs 11,460 lbs).

So lets do some real math he 322 sq ft in F5 generates about 12.9 Hp
(at 0.04 Hp/ft^2). Now, how much does a 11460 lb boat need to do hull
speed? About 22.7, using the formula:
HP = ((SR/10.665)^3) * DISP
In fact, the Benny can only do a bit over SR of 1.1, or about 6 knots.

Lets repeat for a NS36: 742 ft means 29.7 Hp. To reach hull speed
requires 33.7, so in fact it would have a SR of 1.2, or just under 7 knots.

So it would appear that booby simply doesn't know what it means to do
"hull speed," or, he made the whole story up. Or more likely, both.

BTW, a J/29 in 20 knots with full sail generates over 18 Hp but needs
only 11.9 for a Speed Ratio of 1.34. By my formula it gets to SR of
about 1.55 or close to 8 knots, which, I would think, agrees with the
polar at a beam reach. (Actually, the polar I have for a J/30 shows
over 8, but that's with a large jib.)


then a Nonsuch 36 with 742 sq ft and a hull speed a half knot
higher
would have had no trouble walking away from it.


Jeff, seriously, you CAN'T be any kind of real sailor. LWL is not the
end all for speed.


Of course not. However, I can probably find posts where you claimed it was.

MAYBE you know that. Maybe not. My friend's J29 has
less LWL than the 35s5. He'll exceed his hull speed faster than we
will.


But by how much? Upwind or on a close reach its unusual for a speed
factor of greater than 1.4 or 1.5, where the "standard" is 1.34. On a
Beam Reach in a blow, its possible to do 20% over hull speed.

A real advantage of a lightweight boat like the J/29 (same hull, 2000
lbs lighter than a J/30) is that it it will achieve these speeds in
lighter winds.

A boat like the 35s5 will do better than hull speed, even with
her main on a day like that.


So will a Nonsuch. It isn't a crab crusher: the NS36 SD has a PHRF of
141. There's only about 15 points difference. PHRF is normalized for
11 knots of wind; how much of that difference goes away in stronger
wind? How much is the pointing ability?

Moreover, you've claimed many times that your Benny has a low rating
because it attracts better skippers; it would follow that the Nonsuch
has a high rating because its only sailed, as you claim, by "old men."
Since the ratings are in fact pretty close, it must be that the Nonsuch
is actually faster than your Benny.

Our average over an hour was 6.7 knots.


Which is a full knot under the hull speed of a NS36. Again, you're
claiming that you can beat a full sailed NS36 with only your main.
Nonsense!

The Nonsuch was right there with us for about 3 minutes.


And then he went home? This is one of your little "code phrases" that
really means it was out-sailing you so you tacked away! You love to use
phrases like "boat for boat" and "well sailed" so you can make up any
fantasy you want to make the sale. Face it booby, you're a salesman,
not a sailor!

....
I would certainly admit the the 35s5 is a faster boat than the
NS36


Golly! Really? I thought you said the Nonsuch will walk away from a
35s5.


If you leave the jib at home. Actually, on a close reach with full
sail, the boats might be pretty close in a breeze.



Given that
the Nonsuch is a very comfortable cruising boat that is extremely
easy
to singlehand, that's not much of a difference.


Sure it is because the 35s5 is more fun to sail. And I've sailed a
Nonsuch and a Freedom 36 as well. Mark in this very group owned the
Freedom and it's a great boat, but not the kind of sailing we prefer.


Whatever floats your Clorox Bottle.



And on a close reach
with a breeze, the Nonsuch design holds its own against a lot of
other
boats. I never had any trouble keeping up or even passing most 32-34
footers in my Nonsuch 30 on a close reach.


I'm sure we're all happy that the Nonsuch worked well for you on that
point of sail. We kind of like the 35s5, and the J boats we sail. They
tend to be fun and fast on all points of sail.


So now he's admitting he lied about his "encounter" with a Nonsuch and
reverts to his claim that he has more fun.
