SAFETY REGULATIONS.
This manual contains recommendations and basic rules of conduct for using the boat in complete safety.Although it is not
possible to offer safety information for all potential situations, in general it is recommended that you :
Regularly check which safety requirements are in force.
Maintain the boat and the onboard plants in optimum condition.
Have the boat inspected by the dealer where it was purchased or by an authorised
mechanic at least once every year for your own safety and for maintaining the guarantee.
Always check weather and seagoing conditions before setting out.
For safe navigation, compare the design category of your boat with the table below.
W hen the tank is installed by the yard, the plant is prepared with a ground plait. The
installation of the motor MUST FORESEE A PLAINT CONNECTION to the boat ground plait.
Failure to connect (or failed maintenance) can result in the tank perforating leading to a
serious risk of fire / explosion caused by leaking fuel.
Max number of transportable persones is referred to an established weight of 75 kg per
person (ISO 6185), so always make reference to total maximum transportable weight.
The max weight of the installable motors indicates the maximum overall weight applicable
on the stern board, including any emergency motors. NEVER exceed the stated value.

ALWAYS REMEMBER ABOUT FIRE DANGER .
Fire may be caused by:
Crew negligence when smoking, the presence aboard of flammable liquids, electrical contacts, propulsion motor, errors in fueling, or if
maintenance has not been performed as required.
Once again, it is important that the crew behave correctly and that the boat is kept in order to avoid serious damage to it and to persons.
However, if a fire does occur aboard, stop motor, disconnect the batteries immediately, check to see if it is an electrical component or any case
a small-scale fire that does not involve flammable liquids, in which case use a suitable fire extinguisher to try and put the fire out completely.
Easily flammable products must not be kept aboard.
BATTERY: the battery may cause sparks or explosions. It must be stored in an appropriate
container, easily reached and well aired, AW AY FROM FUEL OR INFLAMMABLE PRODUCTS.
Periodically check that the clips are tight and protect them with appropriate insulation in
order to prevent sparks or the spread of current.
Extinguisher or any other fire-fighting equipment must not be kept in compartments with
key lock, but in easily accessible and clearly indicated locations.
Extinguisher or any other fire-fighting equipment should be checked periodically and
replaced with the same or superior types if expired or inefficient.
Equip the boat with fire-fighting equipment before launch and use.
