Ugh, when Sandy roared through I got absolutely whacked with condensation. The worst I've experienced so far.
I already had Hypervent under my cushions, and I've been running the electric, oil-filled heater. I ran out and bought the foil-backed insulation today, and I've already cut panels for the windows, hatches and the gaping maw of an anchor chain locker that is wide-open to the V-berth.
I need to build a wooden hatch cover for the anchor chain locker, and then put the insulation panel on top of that
I fear that the only real way I'm going to get control of this situation is a dehumidifier. I really don't want another electrical load, another appliance to trip over... sigh.
One of those dry, autumn days would sure help dry out the boat after this storm.
