Categorised 'rough' waters

[Channel Ribs]

I am aware that waters can be categorised as smooth, with 4 grades from A through to D (partially smooth). But is there a way for waters to be given a dangerous or rough category or status?

In particular I am thinking about the waters around Alderney, which are famous for being feisty. Is this recognised by anyone?

Simply put the answer is NO

Cat A-D is for rivers, canals, esturies, sheltered waters etc.

Cat A means Narrow rivers where the depth does not exceed 1.5m

Cat D means significant wave height would not be expected to reach 2m at any time

The waters around Alderney are well outside of this scale.

For coding, licensing, certification etc you use the cat 0-6 scale, ie 3NM from nominated point of departure, 20NM from safe haven etc.

That is what I though, so there is no formal kudos for say Category Z waters?

Aside from the Solent, how many RYA training centers are adjacent to Categorised waters?

loads

To many to list but pretty much everyone operating in a river or estuary.

Reading between the lines of what I gues you want to do.

If you want to run powerboat courses and stay within 3NM of Braye Enterance then your boat does not need to be coded, it will be inspected at your annual inspection by the RYA and will need to be equipped with the list I gave you the other day plus anything else appropraite to your area.

If you want to use the same boat for anything else then it needs to be coded anyway.
