It may be useful for you to retain your craft's biofouling
management information in one place, such as the craft's logbook.
This information could include details of the anti-fouling system
used on your craft, any inspections made and notes on the effectiveness
of the coating system. The anti-fouling manufacturer's product data
sheets may also provide useful information. A diagram of the hull
of your craft showing niche area locations and a summary of plans
for minimizing biofouling (e.g. planned time interval between anti-fouling
system renewals and how the different niche areas will and/or have
been treated) is also useful. Example diagrams are shown at the end
of this guidance. Having this information could also assist interested
marina, port or harbour authorities to quickly and efficiently assess
the potential biofouling risk of your craft and minimize delays to
your journey or trip.
