3. Environmental protection
BAVARIA YACHTBAU has already met the legal requirements referring to exhaust gas regulations with
its choice for the inboard diesel installed. An exhaust gas type-examination certificate can be handed in or
sent on later.
3.1 Fuel and oil
You should be especially careful when filling the tank. A (wet) cloth around the fuel inlet can prevent fuel
from dripping into water. In your engine manual you can also find a diagram with a curve about the specific
fuel consumption thus offering you some good hint on the most favourable engine speed.
For a necessary exchange of oil you should use a suction pump, because you cannot drain it off like a car.
The oil has to be exchanged at least once a year, even in case of a little operation time of the engine.
A well-maintained engine should never leak. But in order to prevent even smallest amounts of oil being
discharged overboard with the pumped out bilge water, the engine bed has been designed in form of a closed
oil sump. All water from this sump, being possibly mixed with oil, has to be pumped into a separate canister
and has to be deposited ashore.
In any case there should be oil-binders aboard.
3.2 Waste
For all water sportsmen it goes without saying: waste is not thrown overboard. This is also true for
biodegradable waste. There should be a regular waste bag or –bin in a locker seat.
3.3 Sound
The wet exhaust pipe of the diesel engine reduces the engine sound considerably. Additionally rubber
bearings, elastic couplings and the engine room insulation minimise sound emissions. Nevertheless you
should not turn up the engine too quickly and, please, reduce the engine speed in waters with dense traffic.
3.4 Swell
Natural bank areas are sensitive against swell. Please keep sufficient berth. Formation of waves, caused by
your yacht, is an indicator of where and when you should reduce your speed to avoid unnecessary swell. Pay
attention to relevant signs.
3.5 Exhaust gas
Check the escaping exhaust gas regularly. The exhaust gas should show neither black smoke nor blue clouds.
In such a case you should either clean the air filter or have a repair shop readjusted the engine.
3.6 Antifouling coatings
The underwater part of the hull of each yacht has to be protected with an antifouling coating because marine
growth means more energy for propulsion. Today there is a wide range of protective paint with various
effects for different bodies of water. Trust the recommendations of specialists for your decision. Coatings
that are effective for years without any grinding in between are especially recommendable.
But if the coating has to be sanded to some extend you should arrange these activities with the port officials.
Generally the ground under the yacht has to be covered with some plastic cloth to collect the rubbed down
dust and dispose it.
3.7 Varnish removers
Most varnish removers contain aggressive substances and should not be used or as little as possible. A
mechanical removal of paint is the much better way.
