I have had this post in draft long enough that spring is almost here. Sorry.
Here are a couple of other things we did this winter that really helped make the boat liveable during one of the coldest and snowiest winters Boston has seen in decades.
We added dry deck type products below the mattress. After doing some price shopping we ended up going with Greatmats Staylock.
These added some great air flow below the mattress that really helped cut down the condensation. Prior to adding these the mattress would feel wet on the bottom. Some of the other liveaboards put some ridged foam down under their mattress to act as a barrier. I don’t think that is necessary if you get air flow with something like this.
We stole this next idea from Andrew, our neighbor who has lived on his C310 for over a decade. We put foil, bubble insulation along the sides of the berth.
This added some insulation to help keep the heat in but more importantly it prevented us from touching the cold sides of the forward berth at night. Andrew has covered his with a felt material. This seems to be a good addition and we would have done that if we were going to be doing this next winter.
With all of the cold weather and snow, close to 100 inches in a one month period, we were never cold on board. The heaters kept us in the low 70s while not having an electric bill over $200 for a month. Moisture issues were minimal and we didn’t have to run the dehumidifier full time. We only had one time when the power went out and we had to use the propane heater. That was during the first blizzard of the season back in late January. We were only without power for about 3 hours.
The ice around the hull got a little nerve racking at times. Hell the US Coast Guard icebreaker got holed the ice was so thick and the commuter boats had to discontinue service to Hingham for close to a month.
The marina had some struggles keeping the water flowing to our boat and the waste flowing away. In their defense, the systems they had in place had worked for the last 15 years without a problem. It was just an exceptionally cold winter. But they kept the docks clear of snow and ice and eventually figured out ways to keep the water flowing.
