A decade or so back, Sailing World did a ''10 Best'' issue and Marmadukes was high up on the ''10 best sailing watering holes on the list''. Alas it has been gone for a while, replaced by a steak joint. There is a new ''sailing bar'' in town about a block from ''Dukes'' that seems to have become ''Dukes'' replacement.
I am not sure what to tell you about the barrier coat peeling off. That is not good news. I would suggest that you need to try to find out what that coating actually is. (It may have just been bottom paint.)In any event, if it is a barrier coat, you should probably remove any of that coating that is not adhered abd apply a fresh barrier coat now. It will be much easier to apply now before you have ever applied bottom paint and before you change water conditions.
(For certain types of blisters fresh water is worse than salt but it can work the opposite way as well)
