If I had my boat on the South Coast I would definitely add her to the list subject to favourable weather of course.
Personally I am not a fan of sailing in close company with a group of boats .If someone wants to keep in radio contact thats fine but sailing in a gaggle I find quite stressfull.
Far better IMHO for everyone to do their own planning then meet up in the pub later /forums/images/graemlins/cool.gif
Your crossing times tally with my experience. 18 Hours is about normal.
If your thinking of going Nigel I would look at the Tide Heights. Knowing that you keep your boat in the same Yard as mine, I assume that, you will need a similar height of tide to get out, as I do.
With a tide hieght of less than 4.1 Metres I've had it. I reckon you will have to return wed or thursday after the weekend. If you tide figures are correct.
What are you trying to do to me .... last few days had company audit ... left me nervous wreck .... now the thought of being stranded loooking at the end of pontoon and a sea of mud ... with my flight winging its way back without me ....
