That you are assuming that every post made in this thread was written specifically about the San Diego Divers Permit, which they were not. When I talk about invasive species, I am not referring to the Divers Permit (which for the hundredth time, does not address that subject), I am talking about an ancillary benefit of hull cleaning. I was responding to Gene C's assertation that "Boats are not bringing in the sea life, the sea life is in the water and simply collects on boats."
