Ground school for sailing

Read the wind on the water.
Dark ripples are puffs. Glassy patches are wind shadows. The water shows you the wind, and this game teaches you to read it.
A coach, not a manual.
Cap’n Pell watches you sail. Luff the sail or crash a gybe and he says so. After every run he walks your track like an instructor at a chalkboard.
A real harbor.
Marina del Rey: the breakwater, the channel, the fuel dock, the traffic. Built from real chart data. Practice the exact landing you’ll make on Saturday.
