Reduce Moisture and Mould Growth on Your Boat

21 November 2022

One part of maintenance that should always be conducted in boats is to retain their relative humidity to a certain level. If you currently own a yacht, you must ensure that its cabin’s relative humidity will be retained at around 30 to 50%. Maintaining this level of humidity allows people inside the cabin to feel comfortable. It can also protect your boat components from damage caused by mould and other damaging elements.

Effects of Excessive Humidity on Your Boat

Once the humidity on your boat exceeds the optimal levels, condensation will start to creep on its surfaces. Warm air features more water vapour than cool air. Hence, relative humidity is expected to increase when warm air cools down. Water will then condensate on the cooler surfaces if the relative humidity on your boat increases drastically. Rainfall, unfortunately, can also increase the air humidity inside your boat.

With prolonged excessive humidity levels on your boat, it may gradually obtain damages that can be costly to repair. Structural damages, for instance, may occur on your boat parts made from fibreglass, wood, and cardboard. Some of them may swell and warp, while others will sag. Leakages may also occur on your boat if the air humidity remains high for a long time. Rust and corrosion will likely build up on metal surfaces too.

Mould growth is likewise expected if your boat retains a high level of air humidity. Without resolving this issue and being exposed to black mould can have detrimental effects on one’s health / respiratory system. Ultimately, high levels of humidity can also lead to electrical problems like short circuits, which can be significantly dangerous.

Decreasing Humidity on Your Boat Cabin

To prevent these issues from happening, you must do everything just to decrease the humidity level on your boat cabin and other parts of your marine vessel.

One great way of decreasing the humidity level on your boat is to maintain proper ventilation. Opening the hatches and doors of your boat regularly can help remove unnecessary air. Another way to decrease the humidity on your boat is to keep water out of your inner sailboat like the bilge. The absence of this air will prevent condensation from developing while you are sailing.

Investing in a dehumidifier, however, is perhaps the best way to optimise the air humidity of your yacht. Buying a dehumidifier from a reputable brand like Breville can ensure that your boat will not attain damage. It can also help prevent illnesses from spreading. One particular product from Breville that you can purchase is the Smart Dry Plus Connect Dehumidifier

Invest in and Utilise Breville Dehumidifier

This humidifier makes everything easier thanks to its Live Humidity Control. This feature lets you set your desired comfort level. The dehumidifier will then do the rest, which eliminates the need to tinker with many settings to keep it running. It can also be controlled through voice assistant or the Breville Home Connect app. This device even has 2-stage air filtration that can remove dust, odours, and other particles inside your boat. Once the dehumidifier reaches your pre-set level it will stop running until the humidity increases again.

One simple but great tip to look after your boat when you aren’t using it is to plug a dehumidifier into the shore power or make sure the boat is plugged into the shore power, so that when you go to use the boat you don’t have a flat battery. Additionally, positioning the dehumidifier above a sink and having the drainage hose of the dehumidifier bypass the catchment tank and feed straight into the sink. This means you don’t have to continuously empty the catchment tank and the water that the dehumidifier filters out of the air goes straight down the sink and out of the boat.
