Council of 20th November 2013, which is in force, your boat has design category: B (C), i.e., the
craft is designed to operate in the following conditions:
Wind (Beaufort scale) up to and including Force 8 (6).
Significant wave height (H1/3, meters) up to and including 4(2) meters.
Explanatory note:
A watercraft given design category B (C) is considered to be designed for a wind speed up to and
including Force 8 (6) and significant wave height up to and including 4 (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.

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.

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.

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

STABILITY AND BUOYANCY
The stability and buoyancy of the craft have been thoroughly assessed by the Manufacture and
certified by notified body 2371 Ceskoslovensky Lloyd 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.
ENGINE INFORMATION

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,

WHEN THE BOAT IS ON LAND/DAVIT OR TRAILER, OPEN THE COCKPIT DRAIN PLUGS SO THAT
WATER (RAINWATER, FOR INSTANCE) CAN EASILY DRAIN OUT OF THE BOAT THROUGH THE
