WHAT YOU'LL LOVE
GARMIN SAIL ASSIST™ FEATURES
View laylines, race start line guidance, enhanced wind rose, heading and COG lines, true wind data fields and tide/current/time slider, wind angle, set and drift, wind speed and more.
SAILING POLARS
Use the polar table to see key data, including how fast you should go at a certain wind angle and speed, so you know whether you need to adjust sail trim.
LAYLINES
See visual guides to optimal tacking or jibing angles — green for port, red for starboard. Laylines help you stay on the most efficient course, avoid obstacles and minimize speed loss from unnecessary maneuvers.
WIND ROSE
See true (orange) and apparent (blue) wind angles overlaid on the chart. The 360-degree display gives wind information at a glance, without needing a split screen, so you can stay focused on navigation and hazards.
RACE START
Stay on top of start-line timing and positioning with visual and timer cues. Race start guidance helps manage crowded conditions and countdowns, so you can focus on speed, strategy and avoiding collisions.
MULTICHART ORIENTATION
Sail with one chart in head-up and another in north-up for better situational awareness. This dual view keeps orientation steady during tacks or jibs, making it easier to track your position and avoid hazards.
