having had a few old boats, I think you are seeing "old" barnacle attach marks...sometimes the scrape and paint is not as good as it should be, and although the barnacle is no longer there, the "adhesive" they use causes a different surface for the subsequent layers of paint to adhere/not adhere...a little old age, a little mildrew/water trapped, a little bottom paint from the 70's and 80's and back then we used some weird colored primers and surfacers to try and get the bottom paint to stick better...
looks pretty good for a boat that age...
