My own 38' Carver must have been set up for inland water use and doesn't even have a Y valve so i am used to having to pump out my holding tank, and they have those facilities in my area. Last year at a Moorings Chart briefing there was mention of the possibility of starting to get pump out stations in the BVI. Has anyone heard about this? Seems like they would have to have a fairly extensive network of these to make a dent in the situation, plus the cats I have chartered don't seem to have that big of a holding tank so would have to pump out every couple of days.
