Finding condensation under your cover? A buildup of moisture and condensation under a boat cover can cause mold and mildew to grow and create quite a problem. This is a common concern because, as luck would have it, the properties that make most fabrics water resistant tend to reduce breathability. A simple fix for condensation issues with a water resistant, tight fitting cover is to install a vent.
There are different types of vents to choose from, but we like the Vent Aire Ventilator. It’s easy to install, affordable, and can be wrapped in fabric for a more uniform look. Since it’s a three-dimensional vent, it’s a good idea to add a screen of Phifertex Mesh underneath the vent to keep rodents and other unwanted critters from crawling up inside. This screen can be added during the vent installation.
Aside from condensation problems, cover vents can also be useful when trailering. Even a cover made with a breathable fabric could fill with air and fly off when being towed at high speeds. Installing an air vent will provide an exit point for that air, and help keep the cover securely in place.
No matter the reasoning, adding a vent to a cover is an easy project you can do yourself. Watch this video to see how it’s done.
How to Install a Vent in a Cover
- Determine where the vent will be located.
- Trace the vent on the fabric.
- Cut a hole in the fabric 1/2-inch from the traced line.
- Cut out Phifertex Mesh 1/2-inch larger than the opening all around.
- Use basting tape to cover the vent in fabric.
- Sew the fabric to the vent across the bottom opening of the vent.
- Baste the vent and mesh in place on the cover.
- Sew through the vent and the mesh to secure.
