  • Keeping condensation out from under the cover

    I'm getting close to putting my boat cover on for the winter and I'm concerned with condensation. I have a nice cover and keeps water out but even if I put the cover on a completely dry boat at 6PM in the middle of the summer, the entire cover will be covered in condensation on the top and bottom by 10PM. It's not a huge deal when you use it every few days in the hot summer sun but a big deal if I'm letting it sit for months.

    Has anyone figured out a way to keep the condensation down? Heaters are out of the question since it's a inboard boat.

    you could try placing a few cans of damp rid under there. you can pick it up from home depot relatively cheap.

      With out a heater, I would use several desiccant bags/cups.

      People use them in semi damp finished basements. Should be available at any big box home improvement store or maybe even wally world.

      Heres a link to some on Amazon;

        Or a box fan.

        Desicants often work until they have absorbed all they are going to absorb. Without being dryed artificially or naturally, they stop doing their thing.

        If you have a spot on the boat that is always the first to be wet from condensation, you might be able to use a water leak detector to turn the fan on.

          hang a 3" black pipe or hose over the gunnel under the cover. put it on the side that gets the most sun. hang a white pipe or hose over the gunnel on the shadiest side or end . The sun will heat the black pipe more than the white pipe ,causing it to draw the air from outside through the boat and out the black pipe. With the circulation happening,you will keep inside dry.

              THAT is freaking ingenious!!! Makes perfect sense. Do you do this yourself? If so, how well does it work? I'd imagine, very well.

                Yup! my granddad built a root cellar that way white pipe on the floor and black pipe on the roof. He dug a ditch 5'deep and 20' long( by hand) and ran white pipe in on the floor. cellar was 12 x 12 and vegetables kept well . I was 10 at the time and never forgot it. Dug the cellar in the side of a hill .

                        I'm having trouble picturing this. Are we talking about just suspending 6' lengths of open pipe over the gunnels; one black and one white? Or are they connected to create a closed system like a radiator?

                          sorry bout that. suspend white pipe over gunnel down to the deck, suspend black pipe just over the gunnel. That will give you good air movement.

                            Don't know if this would interest you, but iboats also has a cover support pole with vent built in. I haven't tried it, but noticed it while I was Windows™ shopping.

                              I would love to see a quick drawing of this if you don't mind. I can picture this 2 different ways and I'm not sure which is correct.

                              A picture is worth a thou...well, you know.

                              Thanks for the idea.
