Brian >From what you have described it is your barrier coat that is failing. It will continue to fail over time and sooner or later (but not necessarily now) you will have to strip it off. At some point is good to get rid of the old barrier coat so that you can inspect the bottom for blisters, cracks, etc ...
If it were me and boat was new to me I would inspect carefully from inside and then if seems to be OK would slap on an ablative paint over the mess and go sailing for year one. I would also put a proper bottom job on my to do list as a high priority for year two or three.
