Antifouling Paint

Our boat has antifouling paint from the previous owner. We exclusively trailer the boat thus the antifouling paint really isn't needed. Now as the years pass more and more of the antifouling paint gets rubbed off and I'm wondering if that will cause problem. Should I be removing it? Do I need to put another gelcoat/paint/sealer on it? Or don't I need to worry about it and spend my time sailing the boat?

I'm lost. The antifouling paint on our boat is powdery and only below the waterline. I doubt much would be left if I would sand it. I think even now it isn't adequate to protect the boat if it where to be moored. To much has been rubbed off.

So I don't get the yearly sanding over 20 years if no new antifouling paint is applied.
