Should a z272 have a water tank?
 

If so where? I just found a listing for z272 claiming it has a 5 gallon water capacity. My 272 doesn't seem to have a tank. I don't really need one but I was wondering where it should be. The sink in the so called head just has a hose hanging down and I've just assumed you put a jug under the sink.

That's how my sink is. It's a portable flexible tank, much like a water "bag". I don't think Mariah equipped the boats with water tanks except for their large cruisers (Z260, Z280, & Z308 MCC's)

This is the exact 5gal tank that Mariah used:

West Marine 5gal Water Tank

With all the other features that Mariah put in their boats it was kinda disapointing to see the "plastic bag" connected to a pump faucet in the boat! Must have been an afterthought or something.

You can get it at Wal-mart for $5.
I must disagree with Z275, I think the fact that it can be removed, cleaned and replaced so easily shows Mariah thought of customer convenience! ;)
