Oval pattern cast iron sinker (A3-10043)

Fendercare Marine's oval pattern cast iron marine sinkers are used to support the safe deployment of mooring lines, as well as navigation buoys, and are available in a range of weights and sizes - from 0.5 to 10 tonnes.

Cast iron sinkers have an extended life span in the marine environment, as unlike concrete, cast iron doesn't lose weight when submerged or deteriorate through erosion. Cast iron sinkers were also originally designed by the Admiralty for Royal Navy ship moorings.
