What is the best shape for a sail?

The best shape for acceleration has the draft fairly far forward. Upwind — When a boat is sailing into the wind, you want sails that are relatively flat. Flatter sails reduce drag when sailing upwind and also allow you to point a little closer to the wind.

How do luff telltales help in sail setting?

Telltales are a very powerful tool to help with sail trim. … Luff telltales show what is happening with the wind as it goes over the luff of the sail. Instead of waiting for the sail to luff and slow you down, using the telltales allows you to correct the sail trim before the sail flaps.
