I have lived on a narrow boat for 17yrs. and have managed to fall into the canal four times, it’s impossible to climb back on board as the boat sides are to high as are the canal sides in lots of places. All I have to do now should I fall in again is pull on the red rope provided and as if by magic a rope ladder appears facilitating my escape, now all I have to do is change my stinking wet clothes and live to die another day.
