One boat sailing up from Australia to Vanuatu reported the keel hitting
a sunfish (see the link below). Does anyone have any experience or
sighting of what a sunfish looks like?

Also a few other boat reported some fish, one was said to be one and a
half feet long, and squids landing on the boat. Does this happen a lot
and would these be certain types of fish and not others? Thanks.

They have since pulled the hydraulic rams out of the boat and sent them
back to the manufacturer and on Tuesday had clear enough water to see
the keel was damaged right on the nose of the bulb. 'We sent a
professional diver down someone who does this all the time and he said
it was definitely a Sunfish*.' Coleman says 'in fact he brought up
some Sunfish skin from the keel.'
* Sunfish The ocean sunfish vies for the title of strangest fish in the
sea. Its Latin name, Mola mola , means millstone. Recorded up to two
tons, this gentle giant inhabits all tropical and temperate seas.
