I was sailing my Laser in my club's Sunday afternoon races and after the start of the first race, I managed to get a small lead on the sailor next to me. He tacked away, for a minute, then tacked back. When he got within a few boat lengths of me, I tacked to cover him. He expressed some outrage and after the race explained. This guy usually sails a Thistle and said that in that fleet, a person doesn't tack and cover in the first leg--that it is bad form. He claimed it would be the same in large Laser fleets. Is this the case?
