Here is a little raw footage shot by Birdseye as I intercepted some of the front runners in the Kite Race from Rotto to Leighton a few weeks ago.
Nothing to get too excited about but it does offer a helpful comparison of the speeds of slalom boards vs kites in the ocean

The breeze is mid teens so pretty underpowered on 7.0 with weed on the fin!
Thanks Col!
