So, are you a structural engineer, numb-nuts? If so, let's have some data
and references. Furthermore, find me one documented case of a modern
cruising sailboat "breaking up" at sea. It's allegedly weak hull just
breaking apart.

Or is it once again the case that you, like every other asshole walking the
dock, have an opinion?

not even close to true. a.) cheap fiberglass boats are not "strong
enough" for
anything other than lite conditions, and b.) pound for pound wood is
stronger.
In fact, glass over plywood is *much* stronger than glass.

I know exactly what catenary means, you semi-illiterate dumb-ass.

Catenary forces are a classic problem in physics, where you have linear
forces in parallel with supporting cables. High tension wires are the
typical example.

When the wires are pulled to the point where they are nearly straight-- like
a forstay and backsay for instance-- the tangent of the incident angle
starts to approach infinity. That's why high tension lines and windward
shrouds are designed to sag, so that the catenary forces are kept within
reason.

Look that up in a college physics text, you high-school educated dip****.

nope. and you don't know the meaning of the word "catenary".

a backstayless rig can indeed do the job under conditions for which the
boat is
designed but it NOT stronger than convential rigs (of the same size and
weigh)
and "catenary forces" have nothing to do with it.

thanks for your ever so kind words.

my remarks come from my personal experience going back 45 years, and from the
people working in the business long term to maintain boats, and from brokers of
potentially ocean going and non-ocean going boats, and naval architects of my
personal aquaintence, and indeed structure engineers, including one -- my
brother -- who used to write technical articles for the Experimental Aircraft
Association.

sorry about your Hunter, dude, but most brokers won't handle one for resale
that has been taken offshore. If you don't believe me, you certainly are free
to ask a few brokers yourself.

btw, glass over plywood (makes for one ugly boat usually, but is rather easily
built in a bach yard) is in fact stronger pound for pound than steel or
aluminum or fiberglass. You have to get to the (damned expensive) exotics to
get a stronger boat pound for pound.

again, sorry about your Hunter.
