Bolt Fixings Anodes require
fixings to vessels for a number of reasons. On GRP / Wooden vessels
obviously welding cannot be acquired. The fixings must pass through
the Hull so that the anode can ensure good electrical bonding via
inboard cables to parts that require protecting externally that is
shaft, rudder etc.
Backing Sheets These black expanded
polyethylene backing sheets are for positioning beneath the anode when fitted
to a wood or GRP hull. They ensure a more satisfactory and shake-proof
installation between two surfaces which may not be absolutely flat.
