Shame I've missed the tube footage!
However, a couple of weeks ago at the end of March I did see something that veered between the comical and the unbelieveably scary. Waiting to launch at Brixham, a family were trying to launch / get off in a sportsboat with a stern drive. Tide was low and the owner didn't want to scrape the gelcoat on the slip, so much faffing about getting everyone onboard ensued.
Next problem - how to get away, as the bow was still facing the slip & I'm guessing only the owner who was holding his pride & joy off the slip could drive it.
With the engine running (not quite sure who started her up) he turns her around, so bow is pointing seaward, much of this is done as he stands on the quarte,r about a foot from the stern leg. Then standing right by the leg he pushes off and climbs aboard by stepping up on the the stern leg itself! This was with a packed cockpit, and the engine running, I could easily see a few opportuniities to lose a foot or worse. Never seen anything like it.
Still, he was right next to the Lifeboat station, so it would have been OK!
