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
18
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.
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.

SAFETY
19 Silver Line S250-S330 Owner’s Manual

STARTING THE ENGINE. NEVER USE A FLAME TO CHECK FOR LEAKS.
DO NOT SMOKE OR USE AN OPEN FLAME WHEN FUELING THE BOAT.

1. AVOID SPARKS AND EXPOSED FLAMES NEAR BATTERY. IT MAY EXPLODE.
2. KEEP BATTERY TERMINALS PROTECTED SO AS TO AVOID A SHORT CIRCUIT OR
CONTACT WITH ANY METAL OBJECTS.
3. TURN OFF THE ENGINE WHEN INSPECTING OR SERVICING THE BATTERY.

ELECTRICAL SYSTEMS - SAFETY RULES
Check condition of battery and charging system before departure.
Disconnect and remove the battery when the craft is in winter storage (cold weather areas) or
long term storage.
ENGINE STARTING
Refer to the engine manufacturer’s manual for correct procedures before using the engine.
BE SURE THE ENGINE IS NOT IN GEAR BEFORE ATTEMPTING TO START IT!
MAN-OVERBOARD PREVENTION AND RECOVERY
Man-overboard prevention.
The working deck has an anti slip surface.
When the boat is underway, the operator and passengers should always occupy designated
seating areas, using handles when necessary. Other parts such as seat backs, cleats, windscreen
tops and rails can be used as handholds to reduce the risk of falling overboard.
