Re: Wind indicator NOT for mast top
Telltales really let you know how the wind is flowing over the sails before any backwinding or turbulence is apparent in the fabric of the sail itself. When using a 150%+ genny, being able to see windflow and what the interaction is between main and genny is very helpful to get the sails working up to their potential. It's amazing how much difference becomes apparent in small adjustments of cunningham, outhaul, downhaul, twist, and sheeting angles. Just a small adjustment in jib tension/angle often gets rid of a lot of turbulence that you might not notice without telltales.
