tractor beams

Since things are a bit slow lets talk the unmentionable, "tractor beams".

I purpose as a starting point a system that adds points of maneuver to another
ship within 18 MU of your ship in the direction designated by the tractoring
ship. The ships plot normaly then then the tracktoring ship anounces its
changes to the tracktored ship. Maneuver points are taken from the tractoring
ship maneuver drive. For each point of maneuver the tractor can add one point
of maneuver to a ship half
its size, two points to a ship 1/4 its size.  All fractions of the
tractored ship are rounded up. A ship can tractor a ship of equal size by
using 2 points of maneuver.

Any idea or modifications?
