Sail Trim Simulator

See the wind through your sails. Sail Trim Simulator turns local wind conditions into an interactive 3D sailboat. Point your phone in a new direction and watch the sails and boat respond to your heading relative to the wind. LOCAL WIND, MADE VISIBLE See how nearby wind speed and direction shape the scene. Explore different headings and watch sail trim change as you turn. THREE DISTINCTIVE BOATS Choose Aurelia, a sailing yacht; Flying Dutchman, a ghost ship; or Skadi, a Viking longship. Discover each vessel’s details, from billowing sails to oars that row automatically in light wind. TOUCH AND MOTION Drag to interact with the boat and move your phone to see its response. Tap the Flying Dutchman to fire a cannon volley with smoke, flashes and sound. A QUIET MOMENT ON THE WATER A minimal interface keeps the focus on the boat, the wind and the water. All three vessels are included, with no accounts, ads, subscriptions or in-app purchases. Requires location access and an internet connection for local wind conditions from Apple Weather. Compass response depends on your device’s hardware; motion access adds movement response. Wind conditions and sailing behavior are approximate. This visualization is not intended for navigation, voyage planning or safety decisions.
