catagory b waters?

On the manufacturers plate on my Humber it says that it is suitable for CAT B waters.

What are the definitions of the water catagories (A, B, C & D), and where can I find them?

I have spent the morning trawling through the MCA website but cannot find it.

I can't remember where I read it, but I'm sure CatB was something like significant wave height of 2 metres, and CatC was less rather than more, with A being able to go completely offshore? - it may have said it in the manual that came with the boat..... I will check when I get home later on.

Humber's smaller boats seem to be design category C, with the larger ones being B or so, I can't imagine a large 8 or 9 metre rib is only good for wave heights of 0.6 metres

I agree - it does seem odd.

Apologies to people reading this thread - Alex's comment referred to some duff information I posted and have now removed!

OK - I've just found this:
http://www.ibinews.com/ibinews/ebb/tech_6_pt1.html
Scroll down 'til you get to 'The Regulation'.

I reckon this must be it! I think the problem was I was looking for 'Waters categorisation' when actually it's 'Design categorisation'. Hope that's cleared things up! This allows for wave heights up to 4m and, as you rightly said Alex, the categorisation goes the other way!

Yup, that does look like it

4 metres significant wave height is quite big though, wonder if that includes swell, or is that like a standing wave or something.
There's a load more stuff on

Hi Guys

Your getting mixed up between RCD cat b and cg cat b waters.

RCD cat b has nothing to do with the coasguard cat waters.

Could you give what you believe to be the correct definition of category B waters, then, please?

That's in the link I posted. So why do you think we are confused?



Or are you referring to my earlier post which was, indeed, incorrect and so I deleted it in an attempt to prevent confusion!
