DESCRIPTION - Handling
I -4-HANDLING
I-4-1-Transport:
Advice for fitting to a trailer is given in the owner's manual, Volume 1.
I-4-2-Storage:
CAUTION
THE BOAT MUST REST ON THE BOW (SEE SKETCH
BELOW)
I -4-3-Lifting: The boat has no lifting devices.
WARNING
THE BOAT HAS NO LIFTING DEVICE SO HOISTING
REQUIRES PASSING SUITABLE LIFTING STRAPS
UNDER THE HULL.
FOR THIS OPERATION USE PROFESSIONAL LIFTERS.
ATTENTION
NO PASSENGERS ON BOARD WHILE LIFTING
WARNING
ALL EQUIPMENT MUST BE UNLOADED FROM THE
BOAT FOR LIFTING.
BEFORE LAUNCHING THE BOAT, OPEN THE PLUG
HOLE (18) TO DRAIN ANY RAINWATER FROM THE
COCKPIT (CLOSE THE PLUG HOLE AGAIN BEFORE
LAUNCHING).

BUOYANCY MECHANISM –Assembly on the Hull
II-1-ASSEMBLING THE BUOYANCY MECHANISM ON THE HULL
1
To facilitate the positioning of the buoyancy mechanism, apply liquid soap (A) to the hull
rails
2
Place the bolt rope (a) of the buoyancy mechanism in the hull rail (b) located in the bow of
the hull. Pull on the buoyancy mechanism until the mini-bolt rope faces the rail.
3
- Proceed in the same way for the other side of the buoyancy mechanism.
- Move the tip of the buoyancy mechanism forwards to fold the outer flap down under the
tip of the hull.
- Pull the 2 tabs of the buoyancy mechanism again as far as possible towards the aft end of
the boat, and try to centre the tip with the bow of the hull.
- Slightly inflate the tip of the buoyancy mechanism to check that it has been well centred
and that it matches the hull perfectly. Begin the operation again if the buoyancy
mechanism is not correctly positioned.

BUOYANCY MECHANISM - Fixing the Flap
II-2-FIXING THE FLAP
4
Fix the external flap using the stainless steel bars and bolts of the buoyancy mechanism
kit. Apply sealing compound on all the screws and in the hull holes to achieve final
tightness.
NOTE:
The buoyancy mechanism is mounted on the hull deflated.
You may inflate the buoyancy mechanism disassembled (pressure
240 mb) and let it stabilize for approximately one hour. Then
deflate it.
If the buoyancy mechanism was stored at a temperature lower than
0 °C, leave it 12 hours at room temperature (20 °C) before folding
it.

smoothly and without haste.

BUOYANCY MECHANISM - Pressure
II -4-1- Buoyancy mechanism inflation
•Place the adapter corresponding to the diameter of the semi built-in valve at the inflator
hose nozzle.
Inflate the buoyancy mechanism, balancing the pressure between the different
compartments until the partitions (a) are no longer visible (pressure = 240 mb)
Never pressurise a
compartment when the
others are completely

Inflating is complete: Screw on the inflating valve caps
NOTE:
A slight air leak is normal before the valve cap is screwed on
Only the caps guarantee final air tightness
II-4-2- Pressure
Operating pressure for the buoyancy mechanism is 240 mb/ 3.4 PSI (middle of the green
zone of the pressure gauge).
Your boat is equipped with an ACCESS pressure indicator that will enable you to read the
pressure quickly and efficiently during inflating (see explanations for use in the section
Inflating System).

BUOYANCY MECHANISM - Pressure
Thus, it is important to anticipate:
Check and adjust the pressure in the inflatable compartments (re-inflating or deflating
as necessary) according to temperature variations (especially when the temperature
varies greatly between the morning and evening in hot climates) and ensure that the
pressure is within the recommended pressure zone (from 220 to 270 mb/green zone).
RISK OF UNDERPRESSURE:
EXAMPLE: Your boat is exposed on a beach in the sun (temperature=50 °C) at the
recommended pressure (240 mb/3.4 PSI). When you launch it (temperature=20 °C), the
temperature and internal pressure of the inflatable compartments will drop simultaneously (up
to 120 mb) and YOU WILL THEN NEED TO REFLATE until you regain the millibars
lost due to the difference between the ambient air and water temperatures. A drop in pressure
at the end of the day, when the outside temperature is dropping, is normal.
RISK OF OVERPRESSURE
EXAMPLE: Your boat is inflated to its recommended pressure (240 mb/3.4 PSI) at
the beginning or end of the day (low outside temperature = 10 °C). Later in the day, your boat
is exposed in the sun on the beach or on a yacht deck (temperature = 50 °C). The temperature
inside the inflatable compartments may rise to 70 °C (particularly for dark buoyancy
mechanisms), doubling the initial pressure (480 mb). YOU WILL THEN NEED TO
DEFLATE the boat to return to the recommended pressure.
CAUTION
IF YOUR BOAT IS OVERINFLATED, THERE WILL BE UNDUE
PRESSURE ON THE INFLATABLE STRUCTURE THAT MAY
RUPTURE IT.
IN CASE OF OVERPRESSURE
“EASY-PUSH” VALVE
Release some air by pressing
the valve knob.

PROPULSION SYSTEM
Comply with ZODIAC recommendations and engine constructor recommendations regarding
engine assembly.

INSTALLATION AND CIRCUIT - Fuel
Changing the filter cartridge:
Comply with Zodiac recommendations and filter manufacturer recommendations
Place a funnel and recovery bowl underneath the cartridge while it is being replaced.
Before changing the filter, make sure the fuel supply line pressure is released.
Please refer to the engine manufacturer's owner manual instructions.
Gasoline is a highly flammable product. TURN THE ENGINE OFF, disconnect the
battery, do not smoke and keep all naked flames well away while you proceed with the
kit installation. Place a funnel and bowl pan underneath the cartridge while it is being
replaced.
Before changing the filter, make sure the fuel supply line pressure is released.
IV-1-4-Using the fuel circuit cut-off valves:
NOTE:
- When you are no longer using your boat, close the fuel circuit
