switch located on the steering console.

CHECK BILGE PUMPS REGULARLY TO MAKE SURE THEY ARE WORKING. CLEAR DEBRIS FROM
PUMP INLETS.

SAFETY
18
STABILITY AND BUOYANCY
The stability and buoyancy of the craft have been thoroughly assessed by the Manufacture in
compliance with the requirements of the Recreational Craft Directive 2013/53/EU.
The craft manufacturer guarantees that the boat meets all safety criteria during normal operating
conditions.
However, the person responsible for operating the craft must always keep in mind that the safety
of the craft and crew should be their priority at all times and that conditions on the water can change
suddenly with little prior notice.
Before using your boat, it is strongly recommended that appropriate training is given to all crew
members in the safe operation of the craft.
IN CASE OF AN ACCIDENT, DO NOT PANIC AND REASSURE PASSENGERS
▪Be aware that your boat, even if damaged, may provide the best shelter and facilitate your
rescue. Never leave the boat whilst it remains afloat. Remember that an inflatable boat, even
when full of water, is virtually unsinkable.
▪If, after an accident, a tube compartment deflates, bring it inside the boat, restore the load
balance to the opposite side of the deflated compartment and return to port at reduced speed.

SAFETY
19 Silver Line S470N Owner’s Manual
▪In case of a collision or an impact with a floating object, stop to examine the hull, the buoyancy
tubes, the motor and its attachments and return to shore at a low speed.
▪Signal for help.
Following an accident and before using the craft again, make sure that it is examined by
your dealer or a qualified technician and any defects are repaired.
NEGLECTING REGULAR INSPECTIONS AND REPAIRS MAY LEAD TO A SERIOUS INJURY
OR DAMAGE AND WILL REDUCE THE LIFE OF YOUR BOAT.
For information concerning safe operation of the engine consult the manufacturers instruction
manual.
Consult your Dealer for more detailed information on this subject before operating your boat.

SAFETY
20
RISK OF FIRE OR EXPLOSION
For information concerning safe operation of the engine consult the manufacturers instruction
manual.
Consult your Dealer for more detailed information on this subject before operating your boat.
AVOID CONTACT OF FLAMMABLE MATERIALS WITH HOT ENGINE PARTS.
Most fires are caused by electrical problems or careless fueling.
In case of fire, we recommend to stop the motor and turn off the battery switch.
Pay particular attention to the fact that a fuel tank and electrical devices are installed on your boat.
This means that there is a risk of explosion or fire caused, for example, by a spark. Be careful and
check systems regularly with a view to identifying leaks or corrosion in the fuel tank and possible
damage to the electrical wiring.
For information concerning safe operation of the engine consult the manufacturers instruction
manual.
