About The Propeller; Behaviour Of The Boat - Nanni N2.10 Notice Et Mode D'emploi

About the
propeller
The propeller is a critical compo-
nent of the propulsion system. It
converts the engine power in thrust.
To be efficient, the propeller must
be perfectly adapted to the boat
and to its use.
In all cases, the propeller should
allow the engine to reach its rated
rpm with the maximum boat load.
A faulty operation of the engine is
often due to an inadequate and / or
damaged propeller.

Behaviour of the
boat
If this is your first boat or if you are
not familiar with the boat, we urge
you to practice controlling the boat
at slow speed as a first step.
Avoid violent manoeuvres or
unexpected speed changes while
sailing. People can fall over or
overboard.
Keep also in mind that the weight
distribution (passengers, equip-
ments, etc.) inside the boat has
an impact on the behaviour of the
boat when cruising. Depending the
position of the load, the behaviour
of the boat may change, particularly
in the case of a planning hull.
The condition of the hull and the
propeller is also a critical factor. A
dirty and / or damaged hull will mo-
dify the behaviour of the boat and
therefore the engine performance.
It can also cause cavitation which
can seriously erode the surface of
the propeller, the drive, etc.
