The single most important thing you can do to prevent mold from growing on your mattress is ensure your boat is properly ventilated. Stagnant air is where mold thrives. If you keep air flowing at all times, especially in the bedroom area, you can prevent mold from becoming an issue. Installing vents and running fans are a few easy ways to improve air circulation around your mattress.

Check for and repair leaks.

If water is getting into your boat, it’s going to be difficult to fight off mold. Inspect all seals on your deck regularly, including hatches, ports, vents, scuppers, etc., for pooling water. Remove any deck rot you come across, fill and reseal the area, install new hardware over it, and apply new sealant. The drier you can keep your boat, the less likely mold is to grow anywhere.

Reduce humidity.

Along with stagnant air, mold loves humidity. Controlling humidity in your bedroom and on deck will help prevent mold from making a home on your mattress or anywhere else. If you’re going to be around to supervise, electric and plug-in dehumidifiers are okay. Chemical dehumidifiers, such as calcium chloride products that absorb air moisture, are going to be the safer option though.
