TackSense

TackSense turns wind direction, heading, wind speed, and gusts into clear point-of-sail guidance, sail setup suggestions, reefing hints, and caution notes.

TackSense is a simple sailing aid that helps you understand your point of sail from wind direction, boat heading, wind speed, and gusts.

Enter the conditions, and TackSense shows a clear visual guide for the sailing angle, likely sail position, reefing considerations, and downwind caution zones. It is designed for quick use on deck when you want a fast sanity check without clutter, accounts, or unnecessary complexity.

TackSense can help you identify whether you are close-hauled, reaching, running, near the no-go zone, or in a wing-on-wing zone. It also provides practical trim suggestions such as when sails should be trimmed in, eased out, or when a more conservative setup may be appropriate.

TackSense is not a chartplotter, navigation system, weather service, or replacement for seamanship. It provides general sail-setup guidance based on the information you enter. Always consider local conditions, sea state, crew ability, vessel setup, and official weather information before sailing.

Built for sailors who want a fast, visual answer to a basic but important question: What point of sail am I on, and how should the sails roughly be set?
