Stability factor

[Guest]

Does anyone know stability factor for cat. 30?ty

Solid!

I'm not sure what you mean by stability factor, but I can tell you it's built like a tank. In a 25 knot blow, no reefs in the sails and heeled at 30 degrees it as sure as anything. I wish I could tell you I was as sure as the boat. At that knid of incline I thought I was going to loose it. I guess it would help if I knew a little more about what I was doing though ;-)Cheers,IanSloop du Jour, C30 #444

Stability Factor is only part...

Stability figures are almost always static tests, that is, in calm water. The dynamic stability of the Catalina and most other boats are disappointing compared to a narrower, full-keel, low-center-of-gravity (low-cg) ocean cruiser.C.A. Marchaj's book "Seaworthiness: The Forgotten Factor" is well worth reading. It discusses this and many other factors, and explains how you can calculate some of these factors yourself.

The exact figures can be calculated from formulas in the Annapolis Book of SEAMANSHIP. Capsize value is below 2, 2 or higher is not good, it is calssified as a moderate to heavy cruiser.

capsize screen

The cube-root of the (displacement in pounds divided by 64), divided into the beam in feet.For a C-36 of 12,000 lb. and 12' beam, this is approximately 2.09. The "safe for heavy weather" limit is considered to be 2. There are many other considerations, such as dynamic factors, range of positive stability, and so forth.
