Rallies are held across the UK and overseas. They range from day sails and short camp cruises in sheltered waters, to coastal expeditions over a couple of weeks. They are always an occasion for socialising, making new friends, comparing notes and boats and lots of picnics! You can sail in company or you can sail alone - the DCA does not over organise; join in as much or as little as you wish. At some rallies people all launch from the same place; at others they launch at different locations and meet up at a designated spot.
The DCA does not run a safety boat. Dinghy cruising on exposed tidal waters is for experienced sailors only. Individual sailors must decide whether they and their boat can handle the expected conditions. Always check marine weather forecasts and local conditions before you sail, and remember there is no shame in deciding not to sail if you think conditions are more than you or your boat can manage.
