I’ve been keeping an eye on Bartimaeus remotely. The small electric heater on board seems to be keeping the inside safely above freezing. So far the external temperature has only strayed below zero very briefly, which is fortunate because there is little I could do if the cabin did start to get too cold. I phoned about progress on the repair of the heater last month. I was told that it was fixed, but that they hadn’t yet found the time to get to the boat to re-install it. This week I got a follow-up email saying they hope to visit next week.
