This sail analysis highlights boat-to-boat performance for sailing races. It focuses on tack/jibe recovery times so you can identify which boats regain speed fastest after each maneuver.

Leg performance matrix

Compare each boat by leg: average speed, made-good speed, point-of-sail split, and maneuver density. Made good

Tack & Jibe recovery

Turns are detected as significant heading changes. Recovery time measures how long it takes to return to pre-turn top speed within 5–60 seconds after each maneuver.

Start line analysis requires a race start time, start line (RC End + Pin End), and at least one course mark.

Polar Performance Speed vs. wind angle

Requires sailing data with wind direction

Pick a leg to compare every boat over it. Each boat is measured over its own rounding times for that leg, so elapsed time and distance sailed show who sailed the leg best.

Made-good comparison

Average made-good speed for the selected leg. Toggle VMG/VMC in the Tack Analysis tab or map settings.

No leg selected.

Distance sailed

Path length each boat sailed over this leg. A fuller bar is a tighter line — the shortest distance for the same marks. Value shows nautical miles and the extra over the leader.

No leg selected.

Final standings for the race — ordered by finish. Elapsed time and distance sailed are measured from each boat's race start to when it crossed the finish line.
