Holding Tanks
 

I know this is a stupid question, but I will ask it anyway. Can anyone
tell me what is being done in the so called "NO DISHCHARGE ZONES" with
gray water? If nothing can be legally discharged, how big of a holding
tank does a 57' boat with a draft of 7' need to be?

I've heard that most of the gulf coast marina's pump out stations can
handle boats with less than a 5-6' draft. Are there pump out boats that
come to you? Do you have to go out of the 3 mile limit to dump your
tank?

Any information I can get will help. I need to get the tanks in before
I can put in the engine.

No discharge zones mean that you can't use a Lectrasan or any type I
unit that treats and discharges. All black water (toilet waste) must go
to a holding tank. Grey water discharge is fine... you don't need a
tank for that.

Maybe my memory is failing. . . I sail a race out of Chicago a while
ago, and I thought I remembered the gray water drained into a tank.

Gray water can legally go directly overboard in all US waters except for
a few landlocked inland lakes...the only coastal waters in which gray
water--and bilge water too--cannot go overboard are some very small
parts of the FL Keys National Marine Sanctuary, where you can't anchor
either.

Below Tampa Bay, the "3 mile limit" in the Gulf has been extended to 9
miles.

However, the Keys and Destin Harbor are the only "no discharge" waters
in the whole Gulf...the discharge of treated waste from the CG certified
Type I or II MSD is legal everywhere else. So if you want to avoid the
pumpout/dump hassle altogether, you may want to consider adding an
Electro Scan (new name for the newest version of the Lectra/San,
introduced last fall) or PuraSan to your system. I wouldn't recommend
eliminating a tank altogether, but you can certainly go with a LOT
smaller tank that you'll only have to use if/when you visit the Keys or
Destin Harbor.

It may have...but there's no legal requirement that says it had to.
