Electric Hydrofoil Surfboard.
This image represents the first occasion ever that I have seen and photographed such a recreational craft. I captured a series of images of the board and its rider on the 17th of June 2023 when I was a passenger on the preserved steam ship SS Shieldhall which at the time was setting off on an excursion to the Solent and Portsmouth Harbour. The image shows the Rider and his board in Southampton Water not far from the Hampshire village of Hythe. A quick search of the Internet on my part did not provide me with absolute confirmation as to the name of the board. I might have to be forgiven therefore for the name given to the image because it is of my own creation. Had I had a marketing background (which I don't) I might have come up with the name of E-foil or E-seaboard. It is certainly a board, it has a hydrofoil that cannot be seen in the image and it is driven by an electric motor that is probably powered by Lithium batteries. If you look closely at the rider's right hand you can see what I think is the board's motor controller.
