Level of fouling

A method for rapidly characterising biofouling on the submerged surfaces of boats or ships. The LoF scale

  • It is a ranking scale with six categories ranging from zero to five
  • Categories are based on the amount of biofouling you can see on a vessel’s submerged surfaces
  • It is a straightforward method for consistent scoring of vessel biofouling that can be related to biosecurity risk
