This is most useful in races such as the Newport-Bermuda,
where the ocean currents are critical to the tactics. Changes
in sea temperature are good indications of ocean current.
Sea temperature can be useful in other ways too; water
flowing out of rivers differs in temperature quite markedly
to the sea, and this can assist in choosing a favourable
current.
