Your boat already carries the sensors to know how well it's performing. The regulator logs speed, wind, RPM, and motion together and builds your boat's own best polars — then compares live data against them, so you can tell good trim from bad and a clean bottom from a fouled one.
Boat speed is logged against apparent wind speed, wind angle, and measured sea state, building a polar from how your boat actually sails — every point of sail, flat water to chop. Compare live speed to that polar to dial in trim.
Under power, speed is logged against RPM, headwind, and sea state, so you can see what your boat really does in flat water versus a head sea — and spot when you're down on usual performance, often the first sign of a fouled bottom.
Rough water slows every boat, so a fair comparison has to account for it. The onboard 6-axis motion sensor measures sea state directly and logs it alongside speed, so today's numbers in chop are compared against your own best speed in similar conditions rather than against flat-water figures. The result is a polar that reflects how the boat performs sailing, motoring, in flat water, and in chop.
The motion sensor that measures sea state also tracks heel, pitch, and slamming. Alongside speed, that gives a read on ride comfort — useful for choosing routes, anchorages, and sail plans that keep the crew happy, not just fast.
You choose the speed source: speed through the water (STW) or speed over the ground (SOG). They answer different questions — a shortfall against SOG points to adverse current, while STW isolates the hull. The two are never mixed.
Every boat that opts in contributes anonymized performance to a shared dataset, which answers questions no single boat can: which hull shapes hold speed in a seaway, how much a fouled bottom really costs, how boats of a given type compare. Highlights surface on the public fleet stats and leaderboards.
