Notice To All Shipowners, Fishing Vessel Owners, Agents, Shipmasters, Skippers, Fishermen, Yachtsmen And Seafarers
The Marine Casualty Investigation Boards Report into the sinking of the yacht Megawat - 25 May 2005 found evidence of pitting corrosion of the rudder stock as a result of the incompatibility of the antifouling coating and the aluminium rudderstock.
The antifouling applied to the yacht was copper based which the manufacturer does not recommend for use on aluminium. The rudderstock was aluminium and as a result it was found pitted on the exposed part between the top of the rudder blade and the bottom of the hull.
While it is important to note that this pitting was found not to have had an influence on the failure of the rudderstock, this finding highlights the need to ensure that any antifouling system is compatible with any materials it is applied to. The manufacturers application instructions should be carefully read and adhered to.
