Standard Electric Cabin Heater
We have some items which are AC powered which can help you get rid of that terrarium effect. One of the first things you might consider is going with just a stab standard electric cabin heater. A number of cabin heaters have a setting so that it only comes on when the temperature gets very cold. You can set the thermostat down to 38 degrees, so when it's too cold to be on board the boat but still above freezing, the heater will just be off and it's not a problem. But when it drops down to the near freezing temperatures the cabin heater comes on and that can help protect your potable water systems, sewage system, and even your engine compartment. So that's one possible option.Cabin Heater
The other item is just our portable cabin heater. This is a great heater especially for liver boards who just need a little bit of extra warmth at night. It has an adjustable thermostat so you can set it for any temperature. It has four different speeds on the fan but in addition it has a frost setting so that you can set this on the little blue stars and at that setting it'll turn on automatically at 38 degrees to keep the interior of your boat from getting frosty. This is more of a winterizing or sort of if you want to leave it on all the time when you're not on the boat. This heater has lots of safety features it has an overheat protector if for some reason you block the inlet grill and it is produces up to 1500 watts of power or 5,200 BTUs.Turbo Air Dryer
Another option is something like the turbo dryer. This isn't a heater, it only draws 90 watts, but it has a small heating element and a fan inside of it and the idea is to move slightly heated air throughout your cabin to protect prevent mildew from forming and prevent water from condensing. The turbo dryer is just put down on a flat surface and the heat that it produces in the fan creates sort of a convection cell inside your boat. That'll again keep the moisture from forming so your boat stays dry and you don't get those miserable growths in the middle of the winter. Another model of Turbo Air Dryer is a very small fan and resistance heater inside this aluminum case, very low corrosion and it draws less current than 100 watt light bulb. What it does is circulate a very slightly warmed mushroom of air throughout the vessel and it keeps the air circulating in a convective cell. By doing that it keeps dampness and moisture from forming on surfaces and keeps you from getting that kind of moldy mildewy surface. These are very inexpensive to leave running all the time doesn't draw very much electricity and moves a lot of air again to keep condensation down.Engine Room Heater
There 's one more type of winterizing heater - this is an engine room heater. In this case by extreme heaters. This is a relatively small electric heter, in this case this is only about 300 watts of output compared to 1500 watts, but it's designed to run more or less all the time in your engine compartment. It’s ignition protected so that it's not going to ignite gasoline fumes, and the idea is that by radiating warm dry heat around your engine. It keeps your engine block from freezing. And it and it allows you to keep your boat in condition so that you can use it even in cold conditions. Otherwise if you winterize your boat, with extreme heaters you can keep your boat ready to go using the heater to keep your engine block warm. The other thing this does is get rid of moisture in your engine room so your engine stays drier and in better shape.Cabin Furnace
Another option is to use something like cabin furnace. This is also thermostatically-controlled. And one of the nice things about the cabin furnace is you can turn it down very low and when you do, it slows down both the fan speed and the amount of energy that's coming being consumed by it. So instead of cycling on and off with a thermostat it sort of picks a constant temperature and stays on that. It 's very nice, especially if you're living aboard because you don't have to listen to the fan cycle all the time. When it gets to be down around the dew point inside your boat, you can get a condensation which then causes mildew and your boat can really end up turning into a terrarium accidentally. You know each one of these heaters has a different application but the key thing is it can help you extend your boating season. Into those shoulder seasons we're oftentimes you just put the butt on the trailer and shrink-wrap it and you never use it. Again these are great ways to get more use out of your boat they're very economical to operate.Best branded boat heaters
