Re: SF Bay - how long do you get out of Pettit Trinidad SR?
I think you misunderstand my comment about being wiped lightly. If I put my hand in the water and wipe the slime off it comes off easily and then blue paint begins to release. The diver said the paint was doing fine until the last few months before I had the boat hauled. When it hauled out it was easy to see that the diver needed to scrub it pretty heavily to get the growth off; don't know if it was hard growth or just stubborn slime. The prop was heavily fouled with barnacles where the paint protection had worn away. There was not any soft growth like tunicates or anything hard like barnacles or mussels on it so I assume the paint was still doing it's job to a decent extent.
I have Ultra on my hull again; it's been 1 year and 5 months. Honestly I did not expect it to last as long as it did. Maybe there just is not very much current where my boat is berthed, so the copper is leaching out more slowly.
