I took me a while to work out why almost all yachties use inflatable
dinghys, but if I had thought about my own experience the answer would have been obvious.
I built my first boat, a Hartley ferro
32' myself, and with it I built a little 7' plywood dinghy
I had a girlfriend at the time who latter became my wife and she always had a little trouble getting in and out of the dinghy
from the yacht. One had to step exactly on the centre line or the dinghy became unstable.
On day she steped more than the obligatory fraction of an inch from the centreline and the dinghy, with a speed that can only be described as instantaneous, rolled over putting girlfriend, oars and accompanying parcel in the salty water
The dinghy, of course, was on top of everything.
Well, nothing much was lost
except for my reputation and my girlfriend's pride, but the incident was never forgotten.
In fact I seem to remember it being on the divorce papers.
