Assuming it’s windy:

Practice Starts in breeze
-setting up late or early. Practice timing
-sail trim downspeed is critical
-trim/Hike go timing
-call ability to tack out if need be. do it as early as humanely possible if lane is really bad
-if lane is OK hold on for others to tack out
-if lane is great, almost always do not tack

Tacking
-work on quickness side-to-side

Downwind
-control and quickness; don’t over-roll
-being passive = bad
