OK, I just uploaded an image showing four turns using the Triplanetary - also
Mayday - method of doing vector maneuvering on a hex grid with out needing any
complex math.

The link is

A ship with M-2 represented by four different counters, and a planet.

The red counter is where the ship was, the white counter is where the ship is,
the blue counter is where the ship will be with no course changes and the green
counter is where the ship will be after all course changes. Solid lines
represent the vector paths to the ship's current position and dotted lines
indicate where the ship will be next turn and any direction changes.

These locations can be simply remembered for small numbers of ships, or the
vector lines can be drawn on a paper hex sheet with pencil or a grease pencil if
on acetate.

The arrows around the planet represent the planet's gravity well.

I'll use compass directions for convenience.

Hope this helps.

Cool! I'd like to see this!
