Het aangepaste voorwoord luidt:
Dear student, salaam aleikum.
The paper you're holding in your hands is the product of about thirty years of
'collecting enthusiasm’ of pilots, who were (and some are) involved in training
apprentice pilots. [naam 1], [naam 2], [naam 7],
[eiser] and I were teaching the topics 'Theory of Manoeuvring' and
'Manoeuvring in practice’ to trainee pilots in the Netherlands and some other countries. Some of us are also working as simulator trainer on the MARIN institute in Wageningen, a leading nautical center in the Netherlands.
All of us collected papers on subjects that interested us and that could clarify ships
behavior to our trainees. We tested in real and even made our own models to prove
things. And of course our long experience of being pilot on all kind of ships!
It is definitely not the first book on the subject and it will not be the last, but we think
that most books on the subject are written for the Captains and mates more than
pilots. Often ships behavior in waves is explained extensively and the same time the
famous Becker rudder is just mentioned in five sentences and one illustration,
extensive chapters on anchoring are written and Azipods are ignored.
We don’t intend to explain how to manoeuvre a ship. Manoeuvring is even nowadays a
skill that must be learned in practice. Trainee pilots learn the job on the spot from
their older colleagues. Computers will never change that. Valuable input can come
from simulators and from manned models. But in the end a trainee pilot will learn on
a bridge, standing next to an experienced pilot. Especially when this pilot (and the Captain)
allow him to do the maneuvering and allow him to make mistakes (as long as no
damage is done of course). Sometimes handling a ship is a kind of an instinct.
In this paper it's explained why ships behave as they do. Why makes a bulk carrier the
turn into a basin without any problem and why needs a container vessel with the
same deadweight a push from the tug. Why is a Becker rudder far more effective
than an ordinary one.
When a pilot comes on board and the Captain says: 'Pilot, the ship’s got a Jastram
rudder’, the pilot can respond: ’I heard of them’, instead of looking puzzled.
Or that his CPP is less effective than a fixed propeller.
I hope you will read all these thoughts with pleasure and I wish you safe sailings and a lot of enjoyment in this fantastic job.
Yours sincerely,
