Nutsy,

Hook that shower up to a fresh water tank and you got a pretty good size
soda bottle.

A vessel at sea is a "Derelict" without a crew, be it Sail or POWER.
The range of said vessel is unknown (Could be unlimited) but without
crew I'd dought it.

Give it up Nutsy, You're in a hole of your own making. Digging more only
makes it deeper!
