Alex, Good on you for getting out on the water despite the weather! (Iím also a fan of winter boating.)
Without wishing to provoke any further exchange ref. BIBOA can I just say that my point was why formally set up another club to do similar things that BIBOA does?. The adhoc, informal cruising amongst a bunch of mates is a complement to the more formal cruising not a replacement. (IMHO) Whether those mates are from RIB.NET, BIBOA, Rib International Cruising Club (anyone remember that?!), work etc etc makes no odds does it! One of the benefits I personally have had from BIBOA is making contact with like minded souls to do exactly the sort of thing you did this weekend. RIB.NET equally serves this purpose and you may justifiably feel that joing BIBOA is not worth it. Thats your call and I don't think anyone here, least of all myself would criticise that and I'm sorry if you've taken some of the comments that way!
If you are interesting in more organised/formal cruising BIBOA does have an Easter bash on the Solent arranged which you might find fun. Unless of course you are coming to Cardiff to wave off Messrs Priddy & Co!?
