In the cockpit

See the shift. Make your move.

Watch your speed, read the wind and keep track of the fleet. Show the instruments you need, or simplify the display for a clearer view of the race.

  • Racing compass

    Your heading, the heading after a tack, and a shift bar that fills blue on a lift and orange on a header.

  • Gaps you can see

    See how far ahead or behind you are, and judge your approach to the start line and marks.

  • Local conditions

    Spot lifts, headers and changing pressure, and learn when another boat is taking your wind.

  • Simple controls

    Steer, tack, ease and hoist with keyboard or touch buttons. Best VMG helps hold an upwind or downwind angle while you plan your next move.

Rule 10Port / starboard
STARBOARDPORT

Opposite tacks: the port-tack boat keeps clear

On port: duck astern of starboard or tack away early

Umpire on the water

Know who keeps clear.

Practise port and starboard, windward and leeward, and mark-room. Live umpire calls explain the encounter and suggest what to do next time. Every race uses the same game rules, based on eSailing.
