I have seen this phenomenon with Trinidad-painted boats many, many times. Most frequently with black Trinidad. It seems the paint is reacting with the metal it is in contact with, such as bronze thru-hull or a saildrive housing. The paint discolors and loses efficacy in an ever-widening circle around the object in question. I don't know the specifics of why it happens, but I do know that the people at Interlux are aware of the issue. I wouldn't count on a lot of support from them, however.
