For this drill, boat positioning is somewhat weather dependent, but start by lining up 2 to 3 boat lengths apart, depending on conditions. Too far apart and you risk having different conditions. Too close together and you risk interfering with the other boat. Ideally, you need pretty stable conditions. Each drill starts with boats sailing the VMG mode, which works as baseline from which we can switch to either the high mode or the fast mode. As you focus on each mode, make sure your crew is not only involved in sailing the boat well but gives feedback about gains and losses relative to your tuning partners. Often only small adjustments are needed. A half-inch of mainsheet change can work wonders. If you have a coach, they can help by taking photos or video of each boat’s set up.
