Semi-trad. Lifted the hatch by the tiller to check on a calorifier leak we'd had fixed to see if there was any water in the bilge, decided there was not enough light so lifted the board forward of the hatch which was now bloody heavy due to one of the other owners having fitted checkerplate on top, so started walking it backwards to put it on the towpath. That's correct dear readers, i had forgotten about the lifted hatch and stepped back into thin air, luckily the exhaust silencer stopped my descent to the bilge, but not before i'd barked my entire shin and taken the cabin side to the armpit. Left me with a rather bloody shin and an underarm bruise the size of a small plate.
The leak was fixed though
