MARINE protection


At Northport Marine Services we are continually looking to new products and practices so as to offer our customers the best value for money in all services we offer.

Several of our staff have completed extensive training in the area of vessel corrosion control and advancements in anode protection. As such we  are now offering the new range of Maddox anodes. Maddox anodes are in most instances superior to zinc anodes and greatly reduce woodrot, marine growth and paint blasting. In fact it is possible to overprotect a vessel with zinc anodes, this is not the case with Maddox. Zinc anodes also contain Cadmium which is highly toxic. Maddox anodes do not contain any Cadmium.

 A vessel that is appropriately set up in respect to galvanic protection will require less underwater cleaning and long term maintenance costs. We also supply and fit electrolysis blockers to eliminate stray currents when connected to shore power. Most marinas now state that these are mandatory in order to comply with their bylaws.

We offer comprehensive testing of your vessel’s galvanic and electrolytic protection setup, including the vessels internal bonding condition during your next out of water service and provide a report on our findings.
