I may be mistaken about the San Juans (although when I had my boat in Pt Roberts
and sailed there extensivesly, I was TOLD it was NO DISCHARGE (ie you MUCH lock
your thru-hull closed, even if you have onboard treatment). I know the entire
Puget Sound IS "no discharge".

Nope...it's not. See the EPA list in my previous post. There's only one
small "no discharge" zone in the whole state of WA--and it's only one
marina, so recently made one that it may not even be on the EPA list yet.

I also know that most harbours and bays in the Canadian Gulf Islands and Georgia
Strait ARE "no discharge". I would love to use onboard treatment like the
Lectra-San, but it's not legal in the waters I boat in.

(not up to date: most of the "under review" have been designated)



This IS an up to date list, showing those that actually have been
designated...not nearly as many as were proposed:

But even had the entire proposed list been designated, note that the
first 12 bodies of water on it are all inland lakes, not coastal
waters...and if you plot those in coastal waters, you'll see that
they're all very small harbors and/or very limited areas off federal
parks...not nearly as extensive as the first appear by just reading the
headers.

Remember, Peggie: not everyone boats in waters controlled by US law.

I know...and because in your part of the world, many US boats travel in
and out of Canadian waters, I keep up to date on what's happening in
Canada too.

Because there are some "no discharge" harbors that are also very popular
anchorages, it would not be wise to replace a holding tank altogether
with a Lectra/San...but having both usually means you can get by with a
much smaller tank than would be needed for full time use, while offering
increased freedom from having to find a pumpout while cruising in waters
that don't limit your choice to holding only.
