I never bother plugging the engine exhaust. Most of us have waterlift exhausts that are always “plugged” anyway. The cabin can be a challenge. One problem area is the forward hatch. That piece of metal and Plexiglas is usually at the outside air temp, so any warmer air below rises to the hatch, gets cooled off, and thus you get constant cold air landing on your head AND a lot of condensation that drips on your head or the cushions. I prevent this by getting an old yoga mat and bungee-cording it over the hatch to provide some insulation. I usually put out a big tray of calcium chloride and change it out when it starts looking damp. It is the chemical in DampRid, but can be bought for a lot less money as ice-melt at the hardware store. I will usually stick something under the v-berth cushions to get air under there so they don’t get condensation under them. The Mid-Atlantic is really a pain for “winter”, if it was Florida we wouldn’t have winter and if it was up in the frozen north it would just be below freezing, which means very dry air. We can yank back and forth between freezing and 70+ degree days multiple times. 2 weekends ago I was sailing, last weekend we put antifreeze in, it was 25 degrees this morning, and it will warm up and rain this weekend. Makes for a lot of water! BTW – I keep the cabin heater set on about 50 degrees, I know some people just let the boat assume the outside temp.

One is in the engine, I have seen boats who have plugged the exhaust pipe(s), and maybe even the intake inside the boat – And also in the cabin. I usually leave a hatch and something else on the other end of the boat open, so some air can circulate throughout the winter. Then I began to doubt the usefulness of this a couple weekends ago, when It hit 71 here, and was still 45 down in the cabin. I noticed lots of condensation below, which really bothers me. Does anyone know what the best solution is ? Bill Coleman Erie PA
