Re: SF Bay - how long do you get out of Pettit Trinidad SR?
Maybe there just is not very much current where my boat is berthed, so the copper is leaching out more slowly.
That's not how hard paints work. In a paint like Ultra, the biocide leaches out at a set rate independent of fast or how slowly water moves past the hull. Current or water temperature or any other environmental factor is going to have a negligible effect on leach rate.
