GENERAL INFORMATION
Name of craft Manufacture: GRAND MARINE. Models: G340N and G380N.
According to the Recreational Craft Directive 2013/53/EU of the European Parliament and of the
Council of 20th November 2013, which is in force, your boat has design category: C, i.e., the craft
is designed to operate in the following conditions:
Wind (Beaufort scale) up to and including Force 6;
Significant wave height (H1/3, meters) up to and including 2 meters.
Explanatory note:
A watercraft given design category C is considered to be designed for a wind speed up to and
including Force 6 and significant wave height up to and including 2 m.
BE RESPONSIBLE, TAKE NOTICE OF THESE PARAMETERS WHEN YOU PLAN YOUR NAVIGATION
PROGRAM AND DO NOT BOAT IF THE WIND/WAVE CONDITIONS ARE LIKELY TO EXCEED THESE
PARAMETERS.

SAFETY

MAXIMUM NUMBER OF PERSONS
The Maximum number of people (adults + children) authorized to be on board according to design
standards ISO 14946 and ISO 12217 is given in the technical data sheet in the “TECHNICAL
INFORMATION” section.
DO NOT EXCEED THE MAXIMUM RECOMMENDED NUMBER OF PEOPLE. REGARDLESS OF THE
NUMBER OF PEOPLE ON BOARD, THE TOTAL WEIGHT OF PEOPLE AND EQUIPMENT MUST NEVER
EXCEED THE MAXIMUM RECOMMENDED LOAD. ALWAYS USE THE SEATS/SEATING SPACES
PROVIDED.
MAXIMUM LOADING CAPACITY
You can find the maximum load capacity in the “TECHNICAL INFORMATION” section in this Manual.
It is also shown on the builder’s plate affixed to the hull. Please note that the maximum load capacity
includes the weight of all people onboard, outboard engine, provisions, personal effects, and
additional equipment, minus liquids in fixed tanks. Note that excess and unevenly distributed load
within the boat can create unstable steering conditions and even loss of control.

SAFETY
15 Golden Line G340N/G380N Owner’s Manual
WHEN LOADING THE CRAFT, NEVER EXCEED THE MAXIMUM RECOMMENDED LOAD. ALWAYS
LOAD THE CRAFT CAREFULLY AND DISTRIBUTE LOADS APPROPRIATELY TO MAINTAIN DESIGN
TRIM (APPROXIMATELY LEVEL). AVOID PLACING HEAVY WEIGHTS HIGH UP.
DISTRIBUTION OF LOAD

1. POORLY DISTRIBUTED LOADS CAN DESTABILIZE THE BOAT AND MAY RESULT IN A LOSS OF
CONTROL.
2. THE CRAFT’S HANDLING WILL CHANGE SIGNIFICANTLY DEPENDING ON THE LOAD CARRIED.
3. BE PARTICULARLY CAREFUL WHEN ACCELERATING OR CHANGING DIRECTION.
IT MAY BE NECESSARY TO ADJUST LOAD DISTRIBUTION AND TRIM WHEN NAVIGATION
CONDITIONS OR THE CRAFT’S DIRECTION THROUGH WAVES CHANGE.

IN CASE OF AN ACCIDENT
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.
▪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.

SAFETY
18
STABILITY AND BUOYANCY
The stability and buoyancy of the craft have been thoroughly assessed by the builder in compliance
with the requirements of the Recreational Craft Directive 2013/53/EU. The craft builder 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.
ENGINE INFORMATION
Information about recommended engine capacities, maximum engine capacities, maximum engine
weights for each model are given in the technical data sheet of “TECHNICAL INFORMATION” section.
NEVER USE A MOTOR WITH A POWER OUTPUT GREATER THAN THE MAXIMUM RECOMMENDED,
OR HEAVIER THEN INDICATED ON THE BUILDER'S PLATE. THIS COULD RESULT IN LOSS OF
CONTROL.
