Hi Graham
A: OCEAN: Designed for extended voyages where conditions may exceed wind force 8 (Beaufort scale) and significant wave heights of 4 m and above and vessels largely self-sufficient.
From the Royal Ocean racing club website http://www.rorcrating.com/stix/STIXOwner070501.pdf
Quote:
STIX is the STability IndeX derived by the International Standard for the stability and buoyancy of
boats, ISO 12217-2. STIX is calculated from the physical characteristics of each boat and is a number
generally in the range 5 to 50. In a similar manner to the SSSN system, a higher value suggests
greater seaworthiness. STIX is the product of a number of different safety/stability related features:
Length, Dynamic Stability, Inversion Recovery, Knockdown Recovery, Displacement Length, Beam
Displacement, Wind Moment, Downflooding, and Reserve Buoyancy.

I presume - but am not sure - that this is what the number refers to. Don't know how to evaluate the number though!
Anyone else?

I have seen on a number of boats that there will be different numbers against A, B and/or C. The max number only being certified at a lower category (B or C). Did seem to have some relationship to max number of possible berths for that type. Could have more people on board under B or C category conditions than actual berths on a boat which had fewer than the max number of berths actually available. May have something to do with the fact that I was always looking at the "owners" version with fewer cabins and more storage space.

Ah, so simple and obvious.
A good point to remember, if you are buying, is that you can cram a lot of berths into a boat but that number of people could not possibly live in any comfort if you are sailing for any length of time.

With regard to maximum number of persons, I do not believe it is referring to the number of berths, but simply the maximum number of people who can be on board, even for a day sail.
This from a charter captain whose large catamaran was approved to carry up to 36 people, which he did for day sail charters in the Caribbean.
One of the frightening scenes last winter in the Florida keys were the number of boats that were dangerously overloaded with people including very small children out for the day or weekend. Many of these were chartered small boats. I sometimes think that the Coast Guard ignores these overloaded boats as a form of population control
