The Monster-Sized Story

The Prince of Speed post presents Arthur Mathieu’s 40.62-knot run as a milestone in foil speed sailing. The wording is direct: Arthur entered speed sailing history by breaking the 40-knot barrier in foil with a sailcraft under 10 square meters, recording 40.62 knots on 501 meters with his kitefoil. The accompanying event video reinforces that the claim is tied to Prince of Speed 2021 rather than to an unrelated general kiteboarding run.

Rules of the Beast

This first requires a source that explicitly identifies kitefoil equipment and a roughly 500 m official speed run exceeding 40 knots. The focus is the first documented crossing of the 40-knot barrier in this format, not a general ranking of every later speed result.

How This Got the Nod

Official event social source explicitly names Arthur Mathieu, the kitefoil classification, 40.62 knots, and 501 m distance.
