emissions even more. You should nevertheless avoid accelerating too quickly and reduce the
number of revolutions in sea areas with heavy traffic.
9.4 Backwash
Natural shores are sensitive to backwash. Please keep an adequate distance between your
boat and such shores. The wave profile of your yacht will give you a good idea where to
reduce speed in order to avoid unnecessary backwash. In narrow waterways you should also
heed the relevant notices.
9.5 Exhaust fumes
Regular checking of exhaust fumes is necessary. The exhaust should neither expel black
smoke nor blue clouds. If this is the case you must clean either the air filter of the engine –
something you can do yourself – or a specialized workshop must re-adjust the settings of the
engine.
9.6 Antifouling Paint
The part under the waterline of the Dehler 35 can be protected by antifouling paint, since
growth and vegetation means more energy consumption just to run the boat. The range of
protective paints is large, their effect is wide and therefore the type of paint can be suited to
every type of water.
If the anti-fouling paint needs to be sanded and repainted, discuss the work with your winter
storage firm. During the sanding work the surface under the boat must always be covered
with plastic or foil, in order to be able to dispose of the sanding dust as special rubbish.
9.7 Paint remover
Most paint removers are very aggressive and if possible should therefore not be used.
Mechanical removal of the paint layers, e.g. with a scraper should be preferred above all other
methods.
9.8 Holding tank
If your yacht is equipped with a sewage collection tank, it is essential to take care that in areas
where evacuation is forbidden, the seacock – the connection for direct pumping outboard – is
closed.
The capacity of the tank is limited. You should regularly check the level on the control panel
in the navigation area. As far as possible you should use the toilets in the pleasure harbours
or other places on land.
