Drill the Moments
That Decide the Race.

You already know how to sail. This is where you sharpen the starts, the laylines, and the mark-room calls that cost you places. A full fleet that sails RRS Part 2, honest wind and polars, no scripted answer waiting for you.

A fleet that sails the rules

Port-starboard, windward-leeward, mark-room, penalty turns. The whole fleet obeys RRS Part 2, so your right-of-way calls get tested by boats that actually know them. Foul one and you take the turn.

Honest wind and polars

Hull drag, leeway, wind shadow, puffs, and a real polar curve drive the speed model. Pinch, sail low, or sit in dirty air and your speed shows it right away. Clean lanes are worth what they are worth.

Reps on tap

Start sequences, laylines, mark roundings, the port-tack cross. Run the same situation until the instinct is automatic, any night of the week, no crew to round up and no launch to wait for.

The line is set. Go win it.

Every place you lose on the water starts with a call you can drill here first.
