Jeff,
All I know about the NDZ''s is from the EPA website I listed earlier. None of the areas on the ICW (and obviously offshore) where I sail were on the list. If any of this information is inaccurate, I''d definitly need to know before installing the unit.
Amp requirements are a concern, as my boat is already an energy hog, but it''s more a quality of life thing. I hate being at a great anchorage in the middle of no-where and having to pull up
anchor after a couple of days to go find a pumpout station. So my choice is to explore something like the Lectra San or to increase my holding capacity.
