Categories B, C etc - what does that mean ?

Ive a basic newbie question. I see boats being classified as a category C or B etc and Im only slightly aware of this relating to its seaworthyness.

Can someone outline the various categories and how that relates to what the boat conforms to ?

Thanks.

You have to consider that a manufacturer has to pay some money for the tests in order to receive a Cat B certificate.
Therefore it is a fact that there are Ribs which are really seaworthy and handle the Cat B sea states with ease but nevertheless are only Cat C labeled.

What I want to say, C or B certificate is not really an indicator for a good or bad Rib.

OK, but what about the requirements I would have for say taking a RIB across the Channel, or say going from the South of France to Corsica.

If I get myself a Cat B RIB, dont I need other stuff - VHF, Flares etc ? Legally or just from a common sence perspective.

Realy???...Of course it's not definitive,but I'd say a good indicator that a manufacturer has developed a decent product... and One in which they have confidence.
I'm sure Comercial-Government Procurment agency's would not even consider non C.E,Cat tested Marques.
Like I said,some interesting...AND Hopfully INFORMATIVE Drop Tests on You Tube
.................Cant say I know much about Brigg Rib's.

iirc - CE only covers pleasure RIBs - eg. Delta RIBS are not CE rated, since they sell only to commercial market ?

You don't legally have to have a cat B rib to cross the channel, the categorisation is more to to with what the builder is selling rather than the use that you put it to, if that makes sense. If you wanted to cross the channel on a lilo you could, technically, sort of, in theory, ish!

One example,

the new Shearwarer Cutter has CE Category C.

My Brig 600 has CE Category B.

Not that my boat handles bad but I would prefer the Shearwater for Channel crossings.
