"The ablative paints don’t really ablate unless your going a lot faster than a sailboat.[/QUOTE]"
I don't think most users of ablative bottom paints expect much ablation during the normal use of a sailboat. But you do get ablation at annual haul-out when boats are power washed. To me, this results in much less build-up of bottom paint and the boat may not need to be re-painted in the spring. I've found modified hard epoxy paints (like Trinidad) also work really well during the season but are really difficult to remove when that removal inevitable time comes. I used Trinidad successfully on a previous boat, but was really traumatized -- and exhausted -- when the paint build-up required hours of sanding to remove.

And also completely uninformed.
I think his boat's on a mooring, rather than in a slip, so maybe running the thruster unattended is a bit less fraught with peril. Other than one big clam, I've not had much growth inside the tunnel itself - just around the opening. Less sunlight, for one thing.
