Polar Diagram
Polar diagram showing boat speed (knots) at different true wind angles. 0° is wind from ahead (top); starboard tack runs 0–180° and port tack is shown as 0 to -180°. Wind speeds: 6, 12, 20 knots.

About the TP52
The TP52 is a grand prix with a length overall of 15.85 meters. The polar data on this page is the median Velocity Prediction Program (VPP) output across 58 ORC certificates for this model — a real-world fleet average rather than a single boat's rating.
The polar diagram shows target boat speeds ranging from 5.8 knots to 16.2 knots across various wind conditions and angles. Use these targets to benchmark your upwind beat angle and downwind run angle, then check how your real sailing compares.
