WARNING
During the cleaning or maintenance operation, make sure that nobody
can operate the windscreen wiping system causing damages to persons.
CAUTION
Do not remove foreign bodies activating the blades when the windscreen
is dry.
CAUTION

blades from the windscreen surface.
Before activating the windscreen wiping system make sure that ice has
not stuck the blades on the windscreen surface; if necessary to spray an
anti-freezing agent to detach them.
11.10 SACRIFICIAL ANODES
The submerged metallic parts of the yacht are protected against galvanic
corrosions by means of anodes installed on the stern, on the interceptors
and on the spinners of the propeller shafts. Check for their wear very fre-
quently, as it depends also (and highly) on environmental factors like sea
chains nearby, metal posts or shores, metal hulls moored nearby, electric
devices, etc.. The replacement is necessary when the wear exceeds 50%.
CAUTION
Each time the yacht is lifted, check for the condition of the propeller, of the
protection anodes and of the fastening system.
Replace the anode frequently.
For a spare part of the propeller shaft anode, specify the diameter of the
shaft itself (110 mm).
