Results tell you where you finished.
SailBoss tells you why.

SailBoss transforms raw observations into a complete race model, builds performance intelligence, and provides a command center for understanding what actually happened on the water.

The result is a faster, more accurate understanding of your performance and better decisions in the next race or regatta.

How it works

SailBoss combines fleet-wide GPS data, course information, and proprietary modeling to reconstruct each race as it actually unfolded.

From there, we calculate the conditions and competitive context surrounding every boat, identify the moments that shaped the result, and organize the evidence into a command center that sailors and coaches can explore together.
