In humid areas like South Florida, keeping your cabin dry and mildew free when not using your boat is very important. If you have shore power available, a mini dehumidifier works great. We like models from Eva-Dry. They range from $40 to $85 on Amazon. The EDV-2200 can remove over a pint of water per day and draws very little power and does not create heat. You can install a drain tube in the water tray for continual operation.
