I am not sure what it is called but I have heard that there is a system that rates a boats ability to handle weather and rough seas. Or the way they rate it's sailability? I would like to kinow what it is called and how do I find what your boat is ? Thank you All Alan

Hi Alan, one rating is called capsize ratio. Ours is...

1.94. Those who know say that any number below 2.0 is good. Terry

capsize ratio

I thought about it and realized that it sounds like I am looking for the capsize ratio as you said. What I am looking for is a rating that is given to a boat that shows it's ability to withstand heavy water. I know this sounds dumb but I can't remember the exact name. Inother words a small swing keel boat might be good for small inland lakes where as a larger full keel boat can travel across the ocean. Sorry for sounding stupid. Thanks again Alan

There have been some very seaworthy centerboard boats

Sparkmanm and Stephans' "Finisterre" comes to mind. http://www.sailingonline.com/fullby1107.html Edited to change link.

Old high tech

Reading Ross's link reminded me of another sailboat of the era . In 1957 Ben Seaborn I think his name is. The designer of the Thunderbird, designed a sloop that is 48' in length with a hollow bronze keel (as a water tank).It has a very small adjustable rudder on the keel, a raised saloon and a reverse shear.It also has roll up boom furling It is probably one of the most beautiful boats I have ever laid eyes on . The owner for about 50 yrs has never restored this boat, he has had it meticulusly? maintained by professionals through out it's life . The boat is named Penelicut (nickname Pink Elephant)after a tribe of natives in the pacific NW I believe Some may call it a fat pig but it is a work of art. He wants to sell it so he can Golf more. I think he is about 98 yrs old.I could be so lucky.

You are probably looking for "STIX" ratings

The old 'capsize ratios' were dismissed in the mid 1980s as they omitted important 'form/shape' stabilities. Modern evaluations and comparisons are now based on the STIX formulas: http://www.rorcrating.com/stix/stix.htm ... go to this URL and click on the .pdf links http://www.rorcrating.com/stix/RORCSSI2008.pdf The repressive ultra-bureaucratic EU also now applies different design criteria "CE mark" for "open Ocean" to "inshore" ratings; but, these are viewed as mostly a prevention of sale of 'foreign made' boats, etc. within the EU. I believe it is now illegal to sell any boat within the EU that does not have a "CE mark/rating" ... Overt Bureaucracy intended to control 'everything' at great cost. Some stability and design criteria (for various boats) can be compared at: http://www.image-ination.com/sailcalc.html (old data, not up to 'modern' standards' but still partly valid)
