Condensation Wars, the sequel's sequel: Den-Dry

Okay, so to summarize:  When you live in an impervious fiberglass cocoon, there's no way for moisture to escape.  Breathing, cooking, normal atmospheric humidity, sea spray. . .all of these condense out of the air in your cabin against every cool surface. . .like the hull, walls, and ceiling.  It makes it rain inside sometimes.  Your cushions and mattresses condense water beneath them, resulting in sodden sheets and occasionally an epic explosion of mildew.  To combat this, we've done a number of things which, to a greater or lessor extent, have worked.  We installed a compact compressor based dehumidifier from Eugreen, that we run all winter, which pulls a gallon or more of water out of the air every day.  We've installed insulation on the surfaces that get chilled, slowing down the condensation.  Still, we get condensation beneath our bedding and the salon cushions, and it's damned irritating.

Enter Den-Dry and the lovely folks at RavenWolf Marine.  The product is a mattress and cushion underlayment consisting of little hills of spun plastic with a fabric cover on one side.  You just trim the roll to fit your application, put down the material cloth side up, then put down your cushions.  Viola! There is now air flow beneath your bedding, the moisture can escape, and you can now climb into the V berth without going EEEWWWWWW during the winter.

A little piece of Den-Dry.  The spun plastic assures air flow.
One of our slip-mates got a roll and raved about the stuff, so we thought we'd give it a shot.  The folks at RavenWolf Marine are a joy to work with, btw.  The post office lost our first order and they had us another roll on it's way the next day and were constantly on top of things

Installation is easy and can be done with ordinary scissors, though frankly a set of tinsnips might have been easier.
We've only had the material down for a couple of days, and already it's made a huge difference.  We'll likely be ordering more in the near future for the galley cushions.

  1. Wow... Thanks for the great review! We hugely appreciate the business and the writeup. Let us know if we can do anything else to help out. If the other roll ever shows up, use it for the galley cushions, or gift it forward to another sailor with bunk-funk. See you on the bay in spring!

    1. Hi Bill. Have shared some of the samples with other denizens here at the marina. Your product is something we've needed for some time. Thanks for the support and the attentive service. It's too often lacking these days.
