Your body gives off moisture. Therefore you need some sort of exchange with the outside air. Heating outside air that has just come into the boat increases its dew point so that condensation is less likely to occur. Insulating raises the temperature of surfaces inside the boat therefore condensation is also less likely to occur on those surfaces since their temperature will spend more time or hopefully all the time above the dew point of the air inside the boat.

The key is to know how dew point, relative humidity and temperature interrelate.

You may also want to consider what you are burning. Wood can vary greatly in it's moisture content but averages about 20% for "seasoned" wood. Wood pellets and "dried" woods typically are around 10% so may contribute a little less to the surrounding air.

If you got some "green" wood (could be up to 50% water) you may be adding to your problem as you heat.

The woodstove surely has a chimney!
but it's a good point as to propane...
Woodstoves move a lot of air out of the boat so fresh air must come in or else. Put the stovedraft low near the sole or bilges (with a pipe and so on) because it's noticeable that the warm air in the boat will only go as low as the draft's inlet.More condensation.
Another acquaintance in a steel boat made a point of designing it without insulation so there was a lot of firewood pumped through that boat.A floating Radiator in other words-Save the planet- Insulate.

Thanks everyone for your suggestions. Our V berth is where the major condensation is from sleeping in there everynight. I PBO put 1/2 in foam with a "naugahyde" backing on the walls but it's not keeping out the cold. does anyone know if this type of insulating ever get soaked and become useless? Is there a better product to use on the walls? Thanks again for your ideas..

I would leave a couple of boxes of bicarb open in the V berth until you can sort a dehumidifier. Cheap and effective in small rooms.
