XIII. LIGHTNING PROTECTION
Your boat is protected against lightning. The rigging is electrically connected to ground.
Nevertheless, for your own safety it is important to take certain precautions.
Maintenance
If the boat has been struck by lightning:
- the lightning protection system will have to be inspected to see whether there is any physical
damage, and to check the device’s integrity and the continuity of the grounding circuit.
- All compasses, electrical and electronic devices will have to be examined to identify whether
they have suffered any damage or adjustments to their calibration.
Protection of persons during storms
WARNING
During a storm, you are advised to take the following precautions:
● As far as possible, people should stay inside the boat.
● Nobody should be in the water or be trailing legs or arms in the water.
● While ensuring adequate control over the boat and its navigation, people must take care not
to touch any part connected to a lightning protection system, and especially not in such a way
that would create a bridge between these parts.
● It is advisable for people to avoid any contact with metal parts of the rigging, spars, deck
fittings and lifelines.
XIV. ENVIRONMENTAL PROTECTION AND SAFETY
We advise you to find out about local environmental regulations, and to respect the International
Convention for the Prevention of Pollution from Ships (MARPOL) in addition to the relevant codes
of good practice.
Do not empty toilets or the content of holding tanks close to the coasts or in prohibited areas. Use
the pumping systems provided by harbours or marinas to empty the holding tanks before leaving
the harbour.
CAUTION!
● Most cleaning products, engine oils and hydrocarbons are not environmentally neutral; they
must therefore be discharged at regulated locations (contact the Harbour Master’s Office for
more information).
● Never switch on a bilge pump when there is oil or hydrocarbons in the engine bay as these
products have to be discharged at regulated locations.
● Some products may also present risks to your safety and the safety of other people; this is
why it is essential to read and strictly follow the use recommendations.
● All substances used on the boat must be clearly labelled and stored in a suitable area of the
boat.
