Back then I loved them, found them new and exciting. Went across the channel several times and also across to the Isle of Wright. I remember my friend and I got one hell of a bumpy ride across from Ryde to Southsea? and were bumped about a lot. A few hours later, one sank with loss of life.(March 1972). I took a party of kids to France for a day on one...they were emotionally disturbed and they had great fun. I still think they are excellent. There might be a new one crossing the Forth of Firth I believe.
