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.

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:
