Handle these substances carefully on board so that nothing goes overboard when refilling or
pumping out.
Take special care before draining the boat that there is no oil in the bilge water. Use special oil
sump agents to clean the bilge water or pump this mixture into a separate canister and deposit
ashore.
3.2. Waste
Waste of all sorts must be disposed according to environmental regulations. For this purpose you
should separate the waste on board and dispose of it ashore in the appropriate waste containers
provided by the ports.
Reduce the amount of waste, in particular by reducing packaging! Use packaging that can be
reduced in volume after use.
Glass packagings do not belong in the water either!
3.3. Sound
Sound is also ecological damaged. We have realized some soundproofing measures to reduce
the sound, especially of the engines, below the legal permitted values. Maintain and preserve the
engine room sound insulation. Do not paint over the insulation.
You should additionally choose engine speeds that keep noise within bearable limits.
3.4. Swell
Reduce speed when driving in narrow waters and in the vicinity of protected coastal zones.
Pay attention to relevant signs and speed restrictions.
3.5. Exhaust gases
Exhaust gases are unavoidable. We chose our engines according to the most favourable exhaust
emission values. Pay attention to the colour of the exhaust gas as this can be an indication of a
faulty adjustment of the engine. A blue or sooty appearance is a sign of serious adjustment
errors. Have them repaired!
Do not run the engine as an “auxiliary aggregate” in the port for charging the batteries. Use the
shore connection instead.
3.6. Antifouling, painting
Antifouling shall prevent the marine fouling at the hull below the waterline. Today there is a wide
range of protective paint with various effects for different kind of water. We recommend applying
antitoxic antifouling. Consult your dealer or a specialist shop on this issue.
But if the coating has to be grinded 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 clothes
to collect the rubbed down dust and dispose it.
3.7. Varnish remover
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. Don’t use varnish or paint
removers.
3.8. Black water
The toilet produces most of the black water on board. It is collected in a tank and should be
disposed of on shore by sucking it out. When in a port, it makes sense to always use the port’s
facilities.
Please note that the Baltic Sea Convention, for example, prohibits the discharge of black water
tanks. Some countries have adopted regulations prescribing that the board discharge openings
be sealed.
