Environmental pollution is caused by three kinds of polluting agents:
Non oily and black waters (containing only human organic waste) can be discharged into the open sea. In harbour areas they should be collected into suitable containers and afterwards discharged either during navigation into open sea or by means of special drainage systems fastened to the shore or wheel-conveyed (with optional black water tank).
Soil pollution is caused by discharging waste at shore.
International rules for pleasure yachts essentially prescribe the following:
Please remember that, according to legislation, until such waste is delivered to suitable disposal areas, you will be considered as possessors and therefore indictable in case of unlawful discharge. Should specific cases be missing in the harbour area, the Authority in charge for the disposal is the Port Authority section “Waste Disposal”.
When moored in a harbour, always check that your yacht is not a source of pollution. The environment must be respected and safeguarded, preventing risks for the life of aquatic flora and fauna. It is good practice to leave no trace behind you, to respect laws on safety and environmental protection.
Do not discharge bilge waste, oily residues, fuel or other liquids overboard. Dispose of solid waste and old engine oil in the containers provided at mooring points.
During navigation, it is always necessary to behave suitably and to respect the safety and the comfort of your guests and of persons on nearby boats. Therefore:
It is absolutely prohibited to throw into the sea: plastic materials, synthetic cables, fishing nets, waste bags, floating packaging materials, cordage, paper, rags, glass, metals, bottles, galley utensils and similar. Non-comminuted or unground food waste can be disposed of beyond 12 miles.
Within 12 nautical miles from the coast it is forbidden to discharge into the sea the black water: you must keep off the drain pump, excluding the automatic activation if present.
It is forbidden to use toilets or holding tanks near the shore or in any prohibited area. Use the facilities of the suction port or marina to empty the holding tank before leaving port.
Always consider and comply with local environmental laws and international marine pollution (MARPOL).
Also, you must always respect the rules of good conduct yacht.
When garbage is mixed with other harmful substances having different disposal or discharge requirements, the more stringent disposal requirements apply.
Although discharge at sea, except in special areas, of a wide range of ship generated garbage is permitted at specified distances from the nearest land, preference should be given to disposal at shore reception facilities.
