What advice would you give a customer looking to hire a provider in your area of work?
Your boat in Marina Del Rey is a perfect feeding and breeding ground for organisms such as the tube worm, which are small coral-like strands that grow on unpainted areas of your boat, or areas that have weak anti-fouling paint. The worms rapid growth and colonization can seriously affect the performance of your vessel, especially during the summer months. The winter months will bring very dirty rainwater into the marina that affects the look of your vessel, but worse still, this run off has a high nitrogen content, from agriculture use, and fertilizes the algae, allowing it to bloom out of control. This wide spread growth will attach to your waterline and exposed trailing edge area of your boat, making your boat look unsightly. We are often asked, "why has my boat not been cleaned this month" during the winter months, when in fact it has. The algae, after cleaning, will grow back in days. If your vessel is not cleaned on a regular basis, you will use a considerable amount of extra fuel (20 - 25% tests show, increasing the longer your boat is left uncleaned) getting to your destination, overheat engines due to lack of water flow into cooling systems. And possibly not have adequate safe control of your vessel.
