Clearly, BB wasn't talking about cruising on his C&C 27,

Nope, but he suggested it for his "larger boat" on a cruise where fresh water
was scarce. I guess he needs a lot of dishwater and has dirty decks that can't
be cleaned with a washdown/salt water fed pump!
Anyway...I feel pity for him, so I'll let it go...unless he rejoins the fray!
