hundred's, eh?


That's the claim. And all those cruising cats in the Caribbean got there on
their own bottom.

Given that there's only been about 4 cruising cat capsizes in the last 20
years,
its a little hard to talk about "higher %"


with only 30 cruising cats out there, that is about 14%

How many monos have sunk in the last 20 years?


From winds? with about 10,000 monos out there 2 is about 0.02%.

if you are thinking of boats sinking due to hitting the hits, there is no
difference between cats and mono's.

cruising mono's can't.


That isn't really so. But certainly any weather that has the capability to
flip
a cat could also roll or sink a mono.


it certain is so. wind, and wind alone, can flip a cat. wind can not flip a
mono.


You're right. It only takes about 200 mph winds to flip a cat under bare poles.
It is true that you can flip a cat by carrying full sail in 45 knots and then
not paying attention. Its happens a lot to racing cats, but only once that I
know of to a cruising cat.

Of course, a monohull can sink from a clogged cockpit drain.


In fact, *each* degree of heel on a cat requires _less_ wind than the previous
degree of heel. cat turn upside down at heel anglesof about 30*.


Totally wrong. You should read what you wrote very carefully.




cats are best suited for coastal cruising and voyages well planned around
weather.


So are all but a handful of boats being built today. Despite all of your
claims, a large number of cats are making long passages on a regular basis.

you can flip a cat in 15 knot winds, gusting to 25, if you are not careful.

come on, jeffies. you *claim* to have an associates degree in liberal arts
physics. that mean you *claim* to under the dynamics of wind againt a sail and
how lever stability decreases as the lever grows shorter (due to the cat
tipping, as in heeling). you also *claim* to understand what "end-plate
effect" means, and most assuredly you *claim* to know that a cat has that huge
wind sail (the tramp, deck, and house) exposed as it tilts.

Read what you said - its totally false. You claim to have graduated from high
school, but its looking doubtful.

And its all meaningless, since you haven't produced a single case of a cruising
cat capsizing.

OK -
Prout, 5000 built
Fountaine Pajot - 1300 built
Lagoon - about 1000 built
Gemini - 800

plus dozens of companies that have built a hundred or more - my PDQ has 100
sisterships. There are lots of cats out there jaxie, you just see them where
you are.

Lots of monos sink, though wind may only be one of several contributing causes.
If a mono is dismasted and the mast pokes a hole in the hull, did it sink from
the wind or the water? Do we care?


if you are thinking of boats sinking due to hitting the hits, there is no
difference between cats and mono's.


"Hitting the hits"? Sorry, I'm not familiar with that. A number of cats have
survived with hull damage that would sink a monohull. This was one of the
lessons learned from early designs - cats are now built with collision
bulkheads, watertight compartments, and sacrificial keels. When you do hear of
a cat sinking, the story is usually that it stayed afloat for a day so that the
crew had time to be rescued. A monohull with a serious leak will usually sink
in a matter of minutes.

yup, and it is just as real as parallax's double e in physics.
