I am rigging up a new sail, and I want to place the telltales correctly. A very good sailor at a large regatta told me that the only place that matters on a Sunfish is near the top of the sail right above the fish, but I see people with them all over the place. The winner of the regatta, a Worlds qualifier, used no wind indicators at all (boat, sail, or spars). What to do? Thanks in advance.
