I use the softest possible cleaning pads when cleaning your hull to get the longest possible life out of your bottom coat. Regular dive service has many benefits, some are noticed immediately and others are noticed over a prolonged period of time. Let's start with the immediate impact of having your hull cleaned. First you'll notice an increase in performance and better fuel economy.
Having barnacles, mussels, oysters and three dimensional growth removed from the bottom of your boat will immediately improve the running speed of your vessel and cut down on fuel costs.
In the long term, regular cleanings prevent hard growth from having a chance to embed on your metals as well as your hull and allow me the opportunity to check and possibly change the zincs that protect your metals from electrolysis. Barnacles, oysters, mussels, and 3 dimensional growth can damage your gel coat and attach themselves to your props, shafts, and struts. This can lead to big bills on your next haul out, with yard labor costing as much as $120/hr to grind them off.
With regular preventative maintenance you'll have a much more enjoyable time getting peak performance out of your boat...
