Thanks, I hadn't visited the discussion in while or would have mailed earlier. Thanks for your contribuitions. 114.3 from the factory. This is a helpful reference. Doesn't but quite measure up to the 115 minimum that some offshore races seem to have. There was participation of a Catalina in the Transpac a few years back. I might like to inquire as to whether that skipper had any issues here. Any thoughts who/ how I might make... ]]> feeds@yuku.com (encore125) http://catalina42discussionforum.yuku.com/sreply/3960 Thu, 26 Jan 2006 18:09:49 GMT <![CDATA[ Re: vanishing stability ]]> http://catalina42discussionforum.yuku.com/reply/3959/t/vanishing-stability.html#reply-3959

The correct figures are as follows: -

AVS - 114.3
STIX - 39.86
Ballast Ratio (Lead) 40.5%

US Sailing AVS calculator (www.sailingusa.info/cal__avs.htm) with a 13.83' beam, a 20,500# displacement, an 8,300# ballast weight and a 2.5' estimated canoe body draft (not including keel), I get an estimated AVS of 132.7 for a Catalina 42.

Visit the RYA web-site at: - www.rya.org.uk/images/upl..._11_05.pdf

Scroll down a few pages to the Catalina 42, you will see it has an AVS of 105 which is low. Any off shore boat should have a min of 120.

Wondering if there is a formal word on the Stability number of the MK1. I know these things are variable based on weight, rig, sail plan etc...But wondering if there is a sense, formal or otherwise, of the original factory designed/delivered boat.

I recently purchased hull 125 that was well upgraded by the previous owners for a Los Angeles to Annapolis cruise. I plan to do some blue water as well and in my... ]]> feeds@yuku.com (encore125) http://catalina42discussionforum.yuku.com/topic/1252 Fri, 06 Jan 2006 21:15:22 GMT
