Any ablative paint
Edit: One of the advantages of Ameron abc 3 is that it is a "hard" ablative, also called a tugboat ablative, etc. Unlike many paints it can be drydocked for months without needing to be replaced. I have known people to be hauled for four months, and all they did was a light scuffing to expose some fresh paint, and splash.
I don't know about 7 months, but if it was me I'd take a 3M Scotchpad or similar to it and give it a try.
