...and the verdict is....Not Guilty (of the label Practical Sailor placed on the paint!).
After one of the cleanest bottoms we have ever had during our normal sailing season last year and a winter sitting in her slip doing nothing but waiting for the spring haul out the bottom emerged as clean as I have ever seen it. The only real damage was from the canvass winter cover hold down lines that rubbed paint off the bottom. The slime that was on the hull pressure washed off easily, my keel held its barrier coat for the first time ever (if you want a job done properly...) and I will be using this no copper paint again!
Very pleased...
