What sort of racing allows modifcation of the main so as to increase area beyond the manufactures specifications?


Don't ask me. I hate yacht racing. I do know some racers will embrace any and all
cheats they think they can get away with.

More roach.

Depends on the gooseneck fitting. Mine is a sliding gooseneck that
can be raised or lowered at will. Oftentimes the gooseneck will
fit an internal track in the mast and although it may have been
riveted on to begin with it is a simple matter to drill out the rivets
and change the location while adding new rivets. This would leave
holes in the mast to show that it was done, however.

More likely is a mainsail cut to lower the boom on the aft end
by increasing the length of the leech on the mainsail. This would
result in the aft end of the boom being lower than the forward
end. The original sail held the boom horizontal, I'm sure.

Good points, all. I actually do think that my boom 'droops' quite a
bit so your theory of the too-long-leech has a lot for it. The sail is
definitively not original (the boat will be feting its 30th birthday
soon...).

I heard a different story about Tavernier. At one time it was
a busy port for exporting pineapples, hardwood, and vegetables.
There were several taverns available for the workers. Word got
out that there was always a tavern near the port . Then the Frenchies
came along and changed the spelling. Your explanation sounds
more plausible.


Yes, I think so. Good story, though.

I believe the gooseneck was riveted to the mast on this vessel when
originally manufactured

I believe so, too (it is definitely not on a rail or track) but will
check next time at the boat (weekend).

Poor fellow! The man lost his life primarily because
of poor design by the naval architect.

Those C&Cs are a death trap in more than one way it seems.

But, to design a cruising boat with a boom so low that it
can smack you up side the head is criminal. I should think
a nice little lawsuit would straighten out C&C and the
negligent designer.

You won't find a Wm. Tripp Jr. designed cruiser with such
flaws.

I' d have to disagree about the poor design by the naval architect
statement - only because there are many an older cruising boat that
don't have the benefit or newer design of today's taller rigs, so they
indeed have a lower (and longer) boom than one's head might prefer in
an accidental jibe. My 1969 Morgan 33 Classic was one helluva boat for
instance, but indeed, the boom was low enough to clobber you if you
weren't careful. When it came to design, Charley knew/knows his stuff.
I would suspect he expected those that were sailing his boats to know
theirs, too.

Anyway, I'd say if you had to place blame, it was negligence on the
skipper's part, and the poor guy that got knocked. Beyond that, what
can you do? Accidents do indeed happen. Sometimes with very
unfortunate and dire consequences.

The airfoil is there in all cases, in this respect; as the sail aqttacks the
wind, reguardless of the angle, some air flows on both sides of the sail.
Wind flowing over the most leeward side of the sail creates a partial vacume
on that side, so with air pressure stronger on one side the sail is
"pushed" or "drawn" to the direction where the low pressure is.
Even with the wind directly astern, a low pressure is created on the front
of the sail, and the sail(boat) is drawn forward. Hope that is as clear as
I mean it to be. Welcome to the intoxicaion of sailing.

OK, that's Bernoulli.

Now I'd suggest you look into Newtonian explanation of lift
ie deflection.

It is a simple matter to derive "Bernoulli" using Newtonian equations and
principals. They are the same thing. One common mistake people have with
Bernoulli is using scalar speed and not vector velocity. If you use scalar
speed, Bernoulli is then only valid in "one" dimensional flow like that
approximated in pipes. Pipe flow observations is what Bernoulli used to
formulate his equations.

Hmm, I still have that High school graduation project I did a few years
back. I explained in it how most of that works and a couple other things
with vector format and diagrams. If anyone wants it just email me.
