3 What Influences the Amount of Biofouling on a Recreational Craft?

 All recreational craft have some biofouling, even if recently cleaned or anti-fouled. The amount of biofouling is influenced by factors such as:

  • - the type, age and condition of anti-fouling coating systems and hull cleaning practices;

  • - operating profile, including speeds, time underway compared with time moored or anchored, water temperature, and where the craft is normally kept (e.g. on land, in a marina or on an estuarine mooring);

  • - places visited; and

  • - design and construction, particularly areas that are more susceptible to biofouling (e.g. rudders, propellers and propeller shafts).

 Actively minimizing the biofouling on your craft will greatly reduce the risk of transferring invasive aquatic species and can also improve fuel efficiency and operating speeds.
