There is no Scottish region or Welsh region and the SW Coast region which existed in previous years is not presently active, although there is a rally at Falmouth as usual.
Rallies are usually very loosely organised.
It is not unusual to go to a rally and not make contact with all of the people attending. Boats are sailed or trailed to rallies from all points of the compass, and if members are to recognise each other it is important to fly the DCA burgee. After a while, one gets to know which pub, or beach barbeque site is favoured. Many people like to do their own thing anyway. It is awarded to the author of the best cruising log of the year to appear in the bulletins - spring to winter issues.
