Hi Duncan,
I'm surprised you haven't received the form from BIBOA. As Julian may not be on the forums for a bit I thought I'd reply.

The itinery is:
Saturday
- meet at Yarmouth at 12.00, lunch at The Wheatsheaf
- leave for Weymouth from 13.30 on
- dinner at Royal Dorset Yacht Club at 19.30
Sunday
- leave Weymouth around 10.00 arriving in Yarmouth in time for Sunday lunch at the Royal Solent Yacht Club
Price is £70 per head, which includes B&B at the Crown Hotel, 4 course dinner at Royal Dorset YC and Sunday lunch at Royal Solent YC.
Hope to see you there!
