Tall Ship Concordia sinks off the coast of Brazil, well trained crew made
the difference between tragedy and just a financial loss.

Never heard of a microburst sinking a vessel or even on the open sea but it
does make sense.
Wrong place at the wrong time.

You would suggest a Hollywood movie as having anything credible to
contribute to this question?

You never cease to amaze me Bob.

Reading this about the subject of the movie would be more useful:

Sorry, long link. Hope it works. You may have to cut and paste. If
it doesn't work, look for the "Read About it Here" link on this page:

http://www.rogerlongboats.com/Stability.htm

The "Albatross" had just about the same stability characteristics as
the "Marques". In the big study I did for ASTA and the Coast Guard,
all the vessels we could get data on that hadn't capsized plotted in a
group up in the top right hand corner of the graphs. "Albatross",
"Marques", and another vessel that had also capsized were down in a
group in the lower left with lots of white space in between. There
were no other vessels down there that had not capsized. It didn't
take a microburst in those cases. When sailing at a normal heel angle
with the deckedge about at the waterline, the "Marques" only needed a
22% increase in wind speed to capsize her. "Albatross" was about the
same.

Never saw the "Perfect Storm" either.
After reading the authors admissions that he knew nothing about the sea or
boats, reading his imaginary scenario about how the boat went down and his
less than respectfull descriptions of the people involved, I didn't just put
the book down but threw it in the trash.
If Hollywood followed reality they'd never sell any tickets.
How's it going Roger?

Going good. I'm designing a very cool boat for a company in China and
starting to inquiries about work that indicate that the economy is
showing signs of life.

I was going to take a winter off from working on my boat but I've had
to put off my planned grand tour of Nova Scotia another year due to
some family stuff. I'm taking advantage of the more relaxed schedule
in the spring to undertake the major project of putting a rather
interesting heating system in the boat. Details he

"Perfect Storm" is actually quite a good book if you simply cut all
the reported wave heights in half. Someone I used to work for did the
stability test on the boat and he told me he didn't think she ever saw
the storm. She had probably rolled over and sunk long before it had
built up into anything remarkable.

How are things in your corner of the world?

Strider is looking great! Like the plan for the cabin/water heater too.
Our weather here in FL has finally come to reflect what we expect in the
winter, weekend was beautiful, mid 70s and clear. Took our pontoon out for
an island visit with the kids on Saturday.
About "Perfect Storm", I have a real problem with people who don't know what
happened/where/how or why projecting thier ideas and opinions as facts. See
it all to much in Gov't and contracting.

I was thinking more like a U-boat....(c;]

Hi, Roger!

Thanks for the link. Our problem in South Carolina is getting a cold
drink. Heating water for a shower just means leaving the sun beating down
on the lazerette where the hot water tank is located and watching the hose
so it doesn't boil to blow the system.

Once they get knocked down, do they stay down ?

I used to race on a Ultra Light Sport Boat that was like that. You'd
be sitting there on the rail, thinking about going out on the keel,
saying to yourself: "It should pop back up any second now." After you
said that 4 or 5 times, and rejected the notion of going out on the
keel, it would in fact pop back up.

It depends on the stability characteristics which are highly variable
from ship to ship. Loading and ballasting can change the answer to
that question even on the same vessel.

I sure wish people would learn how to post links that actually point to
something. Something as simple as copying and pasting a link seems to be
beyond the intelligence of way too many folks these days. . . Sad.
