I'm in a large, deep water marina. I share a waterpoint with about 6 other boats, 3-4 of them usually occupied. One neighbour has been leaving his hose connected to the tap, with the tap open, for well over an hour almost everyday. The first time I found he'd done this I asked him if he wasn't worried about sinking his boat but he just said the hose was shut off at the other end.
Now I've only owned one of those new fangled hoses for a short time myself, and I've never had a washing machine on board (which I can only guess is the reason for such use) so I can't get my head around the risk involved here. The hose just gets left on and forgot about, when I need the waterpoint I feel fine about disconnecting it because it's always bursting out all over the place. I guess it only affects me if he sinks and takes everyone on the pontoon down with him, but how likely is this to happen? My gut is screaming "danger!" but no one else seems bothered.
