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
with 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.
