difficult for mold to get a hold in your boat, keep the humidity low, the space well ventilated, and all surfaces clean and disinfected. Do not leave clothes, paper or food lying around. To keep the humidity low you can use one of many electrical or chemical dehumidifiers on the market. (Figure 3)


Holding tanks: Both black and


gray water should be pumped out and the tank treated with some product that will deal with the anaerobic sludge that builds up inside of them.


Check these: Zincs, bilge pumps,


shaft seals and thru hull fittings should be checked before you leave your boat until spring. Also, make sure there is no oil in your bilge which could be pumped overboard by the automatic bilge pump in your unattended boat. It is also a good idea to use engine fogging oil on outboards or inboard engines after cleaning them off for the winter. (Figure 4) The above are general guidelines.


The best course of action is to use your boat throughout the year. The beauty of


the Pacific Northwest is not diminished by a little drop in temperature, and systems on boats often suffer more from disuse rather than wearing out from overuse.
