It's a 3 day race. Start very early in the morning, sail all day untill late. Barbecue on the beach and sleep in a tent on the beach.
Sailing goes on even if there is no wind (they can peddle if they unhook the mailsail) or lots of wind. They sail on open seas, from Belgium to Holland, on inlakes and they take locks.
Gill was thrilled afterwards. He thought it was an amazing experience. Not my cup of tea tough...
