Rewind a fortnight to the Forth & Clyde. There were we, my dad having driven a good chunk of the way started to do his 3 point turn at the wheel. This is the man whose usual "canal steed" clocks in at 40 odd tons.
So, on semi autopilot, he put the helm hard over and opened up with a WOT blip in exactly the way I would to kick the stern round were I turning a 40 ton narroboat in a circle about 10 foot longer than the boat. Had I stood up to sort the mooring warps 1 second earlier, I'd have been swimming. As it happened I ended up on my @rse on the floor.
Here was someone who has been afloat on a huge variety of boats for the last 60 odd years and it was down to chance that I didn't go swimming. I have knocked my thottle accidentally on a slow cruise at least three times I can remember, both up & down.
The time you need the LJ is when you least expect it.
I bet we all automatically put our seatbelts on as soon as we get in the car......
