The manoeuvring booklet should be available on board and
should contain comprehensive details of the ship's manoeuvring characteristics
and other relevant data. The manoeuvring booklet should include the
information shown on the wheelhouse poster together with other available
manoeuvring information. Most of the manoeuvring information in the
booklet can be estimated but some should be obtained from trials.
The information in the booklet may be supplemented in the course of
the ship's life.
