That’s an interesting thing to see, Warbler. I remember Weston Shore well from my youth, but never saw any hovercrafts landing there. I did regularly see them on the Southampton side of the floating bridge departing to and arriving from the Isle of Wight. I never had the chance of travelling on them, but have gone to the Isle of Wight by Red Funnel Ferry, hydrofoil and yacht.
I have since visited some better beaches than Weston Shore, but back then it was the only beach we could walk to and my parents didn’t have a car.
