While we’ve been away, we’ve relied on shore power to keep the batteries topped up, and to run the little greenhouse heater to keep the cabin above freezing. It is easy to keep an eye on things remotely, so I did so obsessively. In mid-February the shore power abruptly turned off. When it hadn’t come back on after a couple of days, I emailed the marina about it. They told me that our supply had tripped so they checked the power cable. When unplugged, water poured out of the (boat) end. This was a surprise to everyone as the connector is under a shelf inside the cratch cover – how could it get wet at all?
