Anybody have, or know where to get, waypoints for a transatlantic crossing
by ship from Southampton to New York?

We booked the Queen Mary 2 for a crossing from England to NYC in June, and
I'm wondering what the route will be.

In June the route will most likely be a great circle from Lands End to
Grand Banks, and then along Rhumb Lines to Ambrose.

If it was March or April the route may well have been much further
south, maybe as far as The Azores, before heading northwestward
towards Ambrose.

The aim obviously is to make as fast a crossing as possible. In summer
when the North Atlantic is relatively calm one can mostly take the
shortest route, which is the Great Circle. But in autumn and spring it
is often wiser to opt for a considerably longer route to have better
weather.

In the depth of winter, say January and February, it is not uncommon
that the weather systems are pressed so far south that one will have
no real option other than to pass North of them, at or near the Great
Circle.

I doubt anyone at the Shipping Company will be able to tell you much
beforehand any details about the route. Usually the Ships Master will
decide the planned route only some 24 hours before departure,
depending on the wether forecasts. That plan may well change several
times during an Atlantic passage.

Since many years now the Master is adviced by meteorologists from some
"Weather Routing" service that have access to *very* powerful
computers where loads of data about winds and currents etc are updated
frequently.

(I am a Sea Captain, since many years now I work in the archipelago
around home. But previously I have sailed on cargo ships around the
world, and crossed the North Atlantic maybe a hundred times or so.)
