Hypervent Alternative

Some boats have a problem with condensation accumulating under the mattress in their berths (for some reason, we don't see this on Eolian... I don't know why).  There are several products offered to address this problem, but they all seem to have the "marine tax" assessed on them.

I recently received this tip from a fellow boater that addresses this very issue and thought I'd pass it along:
Bob,

As you know we are now living on our boat. The Vberth is our berth of choice but it suffered mightily from condensation under the mattress. We considered Hypervent , $9.69 a linear foot from Defender, 39 inch wide roll, and found it was sold here for $19.99 per square foot. Simple math says this is not a frugal choice. Then we found Keene's Driwall tm, a product used by the building trades to prevent rot and water penetration behind brick ( or similar) wall facing. $179 for 4 foot wide 45 foot roll, immediately a $90 saving even if you have 37 feet left over(it was only sold by the roll, no cutting). I managed to find an 8 foot piece from a builder friend of mine and we installed it. Success! No condensation and dry bedding. Total cost $0, even if I had to pay for it the total cost would have been under $30. Please pass this on to your more frugal readers.
