During our last club race, I was crossing courses with a boat on the starboard tack and I knew I was the keep clear boat. The other boat, a Thistle (and mine is an H216...considerably bigger and scary to a Thistle), properly called "Starboard". What is the proper response to let the other boat know that you know you are the keep clear boat and you will keep clear? "Gotcha", "Right On", "K", "I'm bigger than you" all seem like weak responses.
