Due to the presence of "Lord Kelvin's Balls" on the binnacle this must be an
iron/steel hulled vessel.

The two pure iron spheres mounted one on each side of the compass on the
binnacle for the purpose of correcting compass
inaccuracy caused by the magnetic influence of the iron/steel hull and
referred to, rather irreverently, by mariners as "Lord Kelvin's Balls" after
their inventor.

Picture below is of statue of Lord Kelvin in the Botanic Gardens in Belfast
about three miles from my home. The statue shows him standing in front of a
ship's binnacle and one of the iron balls is clearly visible

Thanks for the explanation. I know about Kelvin as a great man but I
was unaware of his iron balls. LOL
Rather colorful in that picture on Wiki- one blue the other red? I
guess better they not both be blue balls. :o)

One ball does appear to be blue but it is probably poor colour rendition.
Normally they are painted red and green to correspond to 'Port' and
'Starboard'.

Cool. Now did I ever tell you about the Captain of a large container
ship that was observed by one of his hands, going to his cabin every
day opening a small wall safe and reading a small slip of paper, then
putting it back, locking the safe and going on about his duties.
This went on regularly for a number of years. After a bit the aid
was ready to go ashore for his retirement.
So he figured it couldn't hurt to ask the Captain about the slip of
paper. So he did.
Captains response, after realizing that this man would keep his word
and not tell anyone about it., "The bit of paper has just 4 words on
it. Port-left, Starboard-right."
