Learn to Sail: Wind & Trim

Learn the wind before you step aboard. Steer and trim a boat on a live dial, through 12 lessons that change the wind as you get better.

Learn how a sailboat really works: wind, sails and steering, on an interactive dial you control with your finger.

A LIVE WIND DIAL Steer the boat and trim the mainsail and jib while the wind blows. The red no-go zone shows where you can't sail. The telltales on the sails show when your trim is right. The water flows past faster as you speed up. When the boat heels too far or a sail backs, you see it and feel it.

A COURSE, NOT A MANUAL 12 lessons, each with three levels of wind:

• Wind and points of sail
• Trim
• Steering
• Tacking
• Gybing
• Sailing an upwind course
• Wind shifts and gusts
• Man overboard
• Docking
• Heaving-to
• Right of way
• Night lights The wind changes as you go, so you learn to react, not to memorise. Tap the instructions at any moment to pause and read why.

STARS, POINTS AND BADGES Every level gives up to three stars and points for speed and good trim, and sums up what you learned. Share your result as a card, beat your best score, keep a daily streak and collect all twelve badges.

FREE SAILING Set any wind and sail from buoy to buoy: each new one appears in a different direction, so you practise every point of sail. In Light or Dark Mode.
