Trial Manoeuvre Vector

Own ship's trial manoeuvre vector consists of
the following three sections:
The first section is a straight line
continuing on the own ship's current
course and speed. The vector length is
calculated using the own ship's current
speed and the trial manoeuvre delay
time.
The second section consists of a
circular arc between the end of the first section and start of the third
section. The arc radius is determined by the manoeuvre rate of turn
and the manoeuvre speed.
The third section is a straight line showing the final course of the
own ship at the manoeuvre speed.
