Replaced insulation in ceiling, salon outboard & quarterberth

Since moving onto the boat, I have been shocked by the amount of condensation and mildew generated just by our breathing (and cooking plays a part too I guess).  The weather has been chilly and wet, magnifying the problem.  At night we would get dripped on by a solution of condensation mixed with uncured boat resin from somewhere in the ceiling–nasty stuff.

We had the salon ceiling (outboard parts that is) off for the knee project, so I took the opportunity to cut pieces from our leftover ensolite foam to fit in the gaps (leftover from insulating hull after knee repair).  We bought the ensolite as old sleeping pads from the army surplus store (army green!)  Two layers of the foam were the perfect thickness, and if I was careful with the sizing, they would fit up in there and stay all by themselves, without bothering with the contact cement.

In the quarterberth all the pieces had to be glued in place; Karen spent an arduous day in the respirator with the box fan ventilating the quarterberth, coating pieces and the ceiling with contact cement and trying to get them to stick.

We have had no dripping, or water droplets forming on the ceiling over our heads, since then.

    A key for stopping mold,etc is ventilation, not insulation. A boat I looked at buy before we got our Valiant had been sealed up for the winter. The owner was living aboard with plenty of heat and insulation. However, the mechanics are that water vapour will condense on the cold surface and then you get mold.

    We keep our boat well ventilated during the winter ( we don’t live aboard) and do not heat it and have had no mould/condensation problems.

    We always have the galley hatched propped open with a piece of 1″ hose when we are cooking to prevent both the water vapour from the cooking process and from propane burning ( creates H2O). Even on cool evenings we will keep at least one hatch cracked open during the evening to minimize condensation. So far it has been limited to condensation on port glass.

    Good luck; have been following you since the beginning and cannot wait to hear of your trip when you finally cast off the dock lines!

    Fair winds!
