The yard put 2 coats of Z-Spar The Protector anti-fouling
paint on the bottom. This is hard paint that is traditionally used in the tropics. My concern is I am seeing slime on the bow section of the boat already! Not more than a month after she was put back into the water.
I have sailed her a few times since then, so she hasnt been sitting around. It is just a slime coat that can come off by hand with just a swipe, but is this supposed to happen so soon? Maybe, this is common and I just didnt know.
It cost me 2k to get this done, so I want to make sure I wasnt screwed.
As a noobie boat owner in SoCal, you are on the steep part of the learning
curve. Allow me to edjumacate you a little bit:
paint will not eliminate fouling growth, only retard it. Even brand new paint will get slime within a very few weeks in California
, as you have seen. So clearly, it needs to be cleaned. The secret to making your expensive bottom paint
last as long as possible is to always clean it gently. For this to be possible in Southern California
, this means cleaning
every 3-4 weeks. By never letting the bottom become even moderately foul, the paint can always be cleaned with the softest media possible (typically carpet or a white pad), thereby avoiding abrasive cleaning
methods which remove paint unneccessarily. A quality hard paint like yours will perform well for 3+ years when properly maintained. Most boat owners hire a dive service
to regularly perform this necessary maintenance
Know also that in San Diego
Bay, the cleaning of ablative paints (which at least one poster here has recommended to you) has (for all intents and purposes) been banned. FYI, if this is your home port.
