Which boat is most likely to capsize ?

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. Gaz Check out: http://www.image-ination.com/sailcalc.html 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: http://www.rya.org.uk/images/uploade...e_10_11_05.pdf |
