How Do I Stop Condensation Under My Boat Cover?
First, try to reduce the humidity inside your boat. This can be done by opening vents and hatches to allow air to circulate. You can also try running a fan or dehumidifier. If that doesn't work, you can try treating the inside of your boat cover with a water repellent spray. Finally, make sure that your boat cover fits snugly against your boat so that there is no air pocket for moisture to accumulate in.
