The Beneteau and the Catalina have higher CSR making
them more likely to capsize. 2 is the upper limit for
an offshore boat.

The AVS for all these boat sucks. The Catalina and
Tayana can barely go below horizontal! Not good or
not right! Tayana claims a much better AVS than this.

Calculate this stuff yourself.


Thanks Gary.

The AVS value of 110 degrees for Tayana Vancouver 460
was given to me by Tayana along with the report shown on
my web page at http://tayana46.tripod.com/safety.htm.

Looking at the curve at the bottom of this web page
wouldn't you say that this is the correct value ?

The AVS numbers for the Beneteau 473 and Catalina 42
mark II were taken from:

Did the Tayana dealer prepare you for the 12-24 month wait for construction
on a new one? And the unbelievable cost to rig one once it's delivered? ( I
worked on a new 46 two years ago)

As far as capsizing: Unless you plan to start sailing soon, and then take
many lessons, practice on countless trips for a few years and learn to
master each and every one of the mechanical systems aboard before rounding
one of the Capes, you'll face far worse and more probable problems than
capsizing.

And, as your best friend, I would gladly pay you on Tuesday for the George
Forman grill upgrade today on this baby. Burgers and beers in the tropics!
Yum!

Fair Winds and calm sea,

Thanks Whimpie

The boat is almost done and I've already seen several pictures taken at
the factory. Both the dealer and the Tayana engineer I talked to told me
that it's just going to take about 2 more months.

I can ask the dealer if the rigging cost is included in the selling price.

I don't plan on crossing any ocean until 2007 or later :-)

Does it matter? Are you actually planning on sailing out of the bay or
river you live on? Most yacht owners day sail or spend a week in sheltered
bays and never put to sea. My guess is you will be doing the same. All that
is left is Rhetoric.

Apparently you haven't been following. This guy has bought Thailand and is
in no hurry to get there.

ETAP 46DS (standard deep keel)

Maybe I'll just get a Tayana for now and get an unsinkable
ETAP later when I have more money and want to sail across
an ocean :-)

Danny,

Unfortunatly I am periously close to Poopie (love the spelling.) Last
year I bought a bunch of land in Nova Scotia, a 20 year old 33' custom
steel cutter, and moved one to the other. Never sailed before but lots
of time on stink pots. Anyway I got there, after about a week. A
little over 400 miles, on the chart.

I think you are right that he is trolling for amusement. But it IS
amusing. Not only his posts but the dead serious answers intermixed
with the others who have "outed" him.

And, you gotta admit, he must have the hide of a rhino. Or is it
brain. Either way, for now he does make me laugh, if only at myself.

The Angle of vanishing stability,Ballast/displacement and
the Capsize screening ratio are useful in choosing a sailboat.

However, I would not take all these calculated ratio's for granted.
How can you validate these ratio's. The best thing is to corroborate the
designs in real situation. This is very difficult to accomplish. How can
you duplicate a real situation.
Computer simulations can be helpful to validate your design to a certain
extent but never at 100%. Sea trials, track records and past performance in
all imaginable conditions can be very useful to corroborate computer
simulations and to confirm applicable ratio's.

Howard:

You and I are tracking. It is indeed amusing and the answers have been
informative. It's a good group.

How's the sailing in NS in the winter? My brother in-law lives in Portland,
Maine. The combination of the ridiculous fog and the rocky shore make the
case for your steel hull.
