THE IMPORTANCE OF QUALITY HULL-CLEANING
|
|
FOULING ORGANISMS SUCH AS BARNACLES, OYSTERS, MUSSELS, SHIPWORMS, OR ALGAE WHEN ATTACHED TO BOAT HULLS CAUSE DRAG, WHICH CAN SIGNIFICANTLY SLOW THE VESSEL, REDUCE ITS MANEUVERABILITY, INCREASE FUEL USAGE, AND MAY ALSO DAMAGE THE BOAT, PREVENTING THE MECHANICAL PART FROM OPERATING PROPERLY. ANTIFOULING HULL PAINTS OR COATINGS ARE TYPICALLY APPLIED TO MARINE VESSELS TO DETER THE ATTACHMENT AND GROWTH OF “FOULING ORGANISMS” (CALIFORNIA DEPARTMENT OF TOXIC SUBSTANCES CONTROL & INSTITUTE FOR RESEARCH AND TECHNICAL ASSISTANCE, 2012). AS NO ANTIFOULING PAINTS ARE COMPLETELY EFFECTIVE TO PROTECT THE BOAT FROM THOSE FOULING ORGANISMS, IN-WATER HULL CLEANING IS A STANDARD MAINTENANCE PRACTICE FOR BOATS THAT ARE KEPT IN THE WATER.
ANTIFOULING HULL PAINTS AND COATINGS WORK EITHER BY RELEASING A TOXIC CHEMICAL (“BIOCIDE”) OR BY PRESENTING A HARD OR SLIPPERY SURFACE THAT MINIMIZES ATTACHMENT BY FOULING ORGANISMS. THE PURPOSE, FREQUENCY OF USE, AND STORAGE LOCATION OF A BOAT WILL DETERMINE WHAT TYPE OF HULL COATING IS APPROPRIATE. THE BETTER CHOICE FOR BOAT HULL PAINT OR COATING SHOULD BE SELECTED TO MINIMIZES THE RELEASE OF COPPER INTO THE COASTAL WATERS, TAKING INTO ACCOUNT THE COATING’S CLEANING NEEDS, LONGEVITY, AND AVAILABILITY. BUT, FOR THE PAINT TO BE EFFICIENT, RELEASING LESS OF THIS TYPE OF TOXICITY, PRODUCTS, AND METHODS OF MAINTENANCE NEED TO WALK TOGETHER, NOT DEPEND JUST ON THE PAINT, HULL CLEANING NEEDS TO BE EXECUTED CAREFULLY.
INTENT TO MINIMIZE THE COPPER CONCENTRATION IN THE WATER THE CALIFORNIA PROFESSIONAL DIVERS ASSOCIATION DEVELOPED A MANUAL OF BEST MANAGEMENT PLAN (BMP) FOR IN-WATER HULL CLEANING. THE BMPS REPORTED THAT FREQUENT CLEANINGS WITH THE SOFTEST TOOL POSSIBLE, CAN PROVIDE COST-EFFECTIVE FOULING CONTROL, REDUCING UNNECESSARY HULL WEAR, INCREASING VESSEL PERFORMANCE, AND REDUCING FOSSIL FUEL EMISSIONS. THE CLEANING SCHEDULE, AND APPROPRIATE METHODS FOR CLEANING HULL PAINTS, MAY DIFFER FROM COPPER-BASED PAINTS (CALIFORNIA COASTAL COMMISSION, 2012.). THE PORT OF SAN DIEGO STUDY, RECOMMENDS THAT HULLS WITH ALTERNATIVE COATINGS BE INSPECTED REGULARLY.
AFTER DECADES OF DIVING, AND MANY YEARS AS A COMMERCIAL DIVER, WORKING HARD and accumulating knowledge WITH THE BEST COMPANIES IN SAN DIEGO, I STARTED MY OWN BUSINESS. AT HARBOR DIVING SERVICES SD WE provide high-quality in-water boat maintenance, WE ARE ALWAYS UPDATed ABOUT "BEST MANAGEMENT PRACTICES", and EVERYTHING WE DO UNDERWATER, IS THINKING about THE BEST FOR YOUR BOAT, at the same time, respecting THE ENVIRONMENT. GIVE ME A CALL FOR ANY DIVING SERVICE THAT YOU NEED AND I WILL TAKE CARE OF YOUR BOAT. I CAN GUARANTEE THAT YOUR BOAT WILL BE IN GOOD HANDS.
