1.7.10. Propeller
The propeller is calculated according to the performance and designed speed. Watch out for
unusual vibrations in the area of the propeller that could be caused by damages to the propeller.
Notes regarding winter storage
For winter storage, the propeller should be cleaned of possible incrustation of foreign matter,
inspected and the flapping mechanism greased. In case of deformations, dents or nicks, the
propeller must be repaired and balanced by a specialist.
1.8. Ventilation
Ventilation can take place via the existing hatch openings and inlets. The engine room is
electrically ventilated. The air circulation must not be obstructed and the ventilation system may
not be altered.
Good ventilation prevents corrosion, marks caused by damp or mildew. This applies to both
summer and winter. The low humidity in winter during clear weather lets the boat dry well.
Ventilate the boat as often and as well as possible for the sake of
the boat and your own wellbeing. Humidity and changes in
temperature can lead to the precipitation of moisture.
If the boat is not in use for a long period of time stand the cushions upright. Air the cushions
regularly in the sun.
Defrost the fridge / freezer regularly. If the boat is not in use for a long period of time, open the
doors of the refrigerator / freezer to prevent mold growth.
Carbon monoxide can accumulate in closed cabins or cockpits. Carbon monoxide can be
created by
•
emissions from the running engine;
•
at low speed, wind from astern or while the boat is moored;
•
or from neighbouring boats.
Carbon monoxide is an odourless, invisible and extremely
poisonous gas. Inhaling carbon monoxide can result in injuries or
death.
Ensure adequate ventilation!
