I noted corrosion at my keel -probably 30 bubbles 3-5mm in diameter. I removed the paint and there was oxidized lead. This is the first year after fairing the keel and applying barrier coat and antifouling to the keel. It may be from stray currents of neighboring boats . I did not leave the boat plugged in this year except for the weeekends I was there(8 weekends). I am installing a Zinc to the propeller shaft to hopefully alleviate the corrosion of the keel
