Hi Jacob Yes they do talk to each other. We encourage them to do this as when you are trying to judge the position of boats that are only 1 metre long and some 100 to 150 metres away it can be very difficult. I don't know if you are familiar with the rules of racing; there are rules as to who should give way and which boat is the right of way boat. Good skippers will often call out to other skippers telling them that they think that they have right of way or to give them room at a mark or to keep upwind or that they are the starboard boat. On top of this even if you are the right of way boat you still have an obligation to avoid a collision so talking to each other helps.
