When looking through specs on very large cruising yachts I see the terms
referring to "black and grey" water in addition to regular fresh water tankage.
Can someone explain-is this tankage for not potable use, such as heads and
such?

Thanks!

Never heard of black water. However, water that is usable but not potable
is usually referred to as grey water. This would be like water from the
sinks, etc. On land this water is usually used for irrigation usage,
usually watering the lawn and maybe washing the car. Therefore I will make
a guess that black water is strictly from the head. If there is a
separation between black and grey water check to see if the 34(36) has three
holding tanks, one for potable water, another for water from the kitchen and
lavatory sinks, and a third for holding crap and stuff.

This Black/Grey/Water designation is something I see in specs for mega yachts
generally. Like my C&C 32, the 36 has two fresh water tanks.

No holding tank? I guess if you only day sail you don't need one.

Uh, Jeff, the holding tank is not listed under "fresh water" tankage. Remind me
to bring bottled water if I ever pay you a visit!

Zikes!

Context, Bob, context. You made two posts about total tankage, not just fresh water, and
even named the thread "black water."

Since you never stay out long enough to use the head you probably don't appreciate that
black water size can be more important than fresh water size.

My understanding, in a nutshell, is that "black water" comes from the
toilet, and "grey water" comes from the sink.

Sorry, Jeff, but my post about the C&C refers specifically to FRESH WATER.
See below. Your comment also refered to the C&C, so it's you who missed the
context, which was exact.

I win again...a somewhat meager victory, but a victory all the same!

Yahhhoooooie!

So why is grey water and potable water not the same. Why not support a greater
fresh water system overall and eliminate the grey water?

RB

Good Lord!??

Yes, may I help you?
