I've heard different opinions what kind of wire is better for wiring
boats.Could you give me some of your expertise?

The proper wire to use is stranded.

As others have said, the reason for this is that it is better for dealing
with vibration.

Another reason that YOU should use the proper wire is that it could become
very important if you ever plan on selling this boat. If a prospective
buyer has a survey done and the surveyor finds (and he should) that the boat
has been rewired with solid wire you may be looking at a rather expensive
job to restore the boat to a proper wiring configuration.
