Antifouling paints applied to a hull help to prevent the growth of weeds and various types of marine organisms. A vessels anti-foul is an important part of your annual servicing.
Regular (annual) antifouling is recommended and is a good investment. At times it might be tempting to postpone the expense to a second year, or even just another six months, but it may be false economy in terms of higher fuel costs (via increased drag on the hull and prop inefficiency) and lowered protection of the hull surface against osmosis for fibreglass vessels and marine worm for wooden vessels.. Savings of 5 to 10 percent can be attained with a hull wash and new anti foul applied. At Havelock Slipway only quality paint systems are used. In most cases the antifoul is applied by an airless spray unit.
Electrolysis and Anodes
Most boat owners are aware of the damage electrolysis can do to the metallic parts of their vessel in constant contact with the water, and how bonding of these metallic parts can prevent damage if linked to a regularly replaced sacrificial zinc anode.
Havelock Slipway stocks popular sizes of Anodes. Any anode that is eroded by half or more it is recommend that they be replaced.
An annual service has the added benefit of allowing an out-of-the-water inspection of the hull and running gear to ensure that all is well and safe, especially for stern drive vessels. Checks include antifoul and hull condition, anode wear, inspection of the propeller/s for cracks or damage, fastenings are secure, check skin fittings for obstructions and clean where necessary, i.e. shell fish hindering waterflow, check cutless bearings for wear and play, rudder movement and condition. If a problem is detected earlier rather than later, many thousands of dollars in repair costs can be saved.
