It says on catsailing news that the P15 had retired and the mistake was in scoring him.
The way they focus on the corrected time and not the fastest boat, does it make sense to build a boardless rule beater rated slow but actually fast enough? Plus it would be able to take short cuts over the shallow water.

Kind of interesting, the down playing of the foilers. It's a healthy anomaly to have an open race where a H16 gets 2nd.
