I now have a cheap video camera in a waterproof case.

Here are four very brief videos, the first on a day with little wind, the second and third running before a fresh wind and surfing on the swell. The fourth shows the starboard tack of a close haul in moderate wind before it started whipping up. I was sailing from Barfleur southwards towards the Pointe de Saire on the north-east corner of the Cotentin.
