Norm,
What you describe is called a random wire antenna. The wire that sticks up
must be tuned with an antenna tuner which makes up a portion of the above
ground antenna, the other portion of the antenna is the ground. The more
important
part of this equation is the ground.
Also, a dipole in different configurations can be used in sailboats. A
sloper or an
inverted 'V' are two types, or unless you have a lot of free airspace
between masts, an actual dipole.
None of the dipole types require a ground plane because they
are considered balanced antennas. The radio chassis however does require a
good DC
ground with either the random wire or dipole.
