Product Usage Instructions
Inventory
Ensure that you have all the following components:

  • Hull
  • Buoyancy Chamber
  • Optional Accessories

Location of Elements
Refer to the diagram below to locate the different elements:

Handling
Transport:
During transport, the boat must rest on the bow line. Please refer to the diagram below for proper positioning:

Storage
Properly store the boat to avoid damage. Follow the recommended guidelines provided by the manufacturer.

Inflation Procedure
Refer to pages 5-6 and sections 9 & 10 for the inventory, location, and inflation of the boat.

Inflation System
The inflator consists of the following components:

  • Adapter
  • Hose Nozzle
  • Hose Base
  • Inflation Port

Semi-Embedded Valves
To activate the valves for inflation, push the membrane down to open the valve.
Note : Ensure that the pressure is within the optimal range indicated by the green zone. If the pressure is too high, deflate the boat.

Buoyancy Chamber Pressure
The buoyancy chamber should be inflated according to the following pressure ranges:

Compartment Pressure Range (MB) Pressure Range (PSI)
1 0 – 100 0 – 0.06
2 0 – 100 0 – 0.06

**Note:** Avoid under-inflation and over-inflation, as they can pose risks.

Propulsion System
Follow the recommendations provided by Z Marine and the engine manufacturer for optimal usage of the propulsion system. Please consult your dealer for further assistance.

DESCRIPTION

CARACTERISTIQUES TECHNIQUES

NOTE Dimension tolerance: +/- 4 %

NOTE

  1. The maximum payload has been calculated according to ISO 6185 standards. Operating at or near maximum payload is only advised in calm water and at reduced speeds.
  2. Weight shown not including accessories
  3. The recommended power corresponds to the optimum operation of the boat’s capabilities for an average load (4 people.) The minimum power is exploitable in relaxed activities, such as fishing, while the maximum recommended power is destined for performance activities such as water skiing.
  4. Hull dimensions without buoyancy chamber. Use the maximum authorized power with extreme caution (see “Sailing advice” chapter of Volume 1 of the manual.)

WARNING
THE MAXIMUM LOAD INDICATED ON YOUR DOCUMENTS MUST NOT BE EXCEEDED, WHEN THE ENGINE, FUEL, ACCESSORIES, PASSENGERS, THEIR KIT AND ANY OTHER LOAD HAS BEEN ADDED.

BUOYANCY CHAMBER – Main steps

SETTING UP THE BUOYANCY CHAMBER – MAIN STEPS
When assembling the boat, it is important that you follow the procedure in the correct order. Proceed step by step, referring each time to the pages indicated for explanations.

SEMI FLUSH-MOUNTED VALVES

PRESSURE INDICATOR (Screw it in using a ¼ turn to replace the valve cap)

BOAT INFLATION

DO NOT USE A COMPRESSOR OR COMPRESSED AIR CYLINDER.

BUOYANCY CHAMBER – Pressure
INFLATING THE BUOYANCY CHAMBER
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)

Inflating is complete: Screw on the inflating valve caps.
NOTE:
A slight loss of air is normal before the cap is screwed on. Only the caps guarantee final air tightness.

PRESSURE
The correct pressure for the buoyancy chamber is 240 Mb/ 3.4 PSI (middle of the green sector of the pressure gauge). Your boat is fitted with an ACCESS pressure indicator which provides a quick, efficient readout during inflation (see explanations for use in the “Inflation system” section). The temperature of the surrounding air or water will proportionally influence the level of internal pressure in the buoyancy Chamber Ambient temperature buoyancy chamber internal pressure

  • +1°C +4 mb / 0.06 PSI
  • -1°C -4 mb / 0.06 PSI

Thus, it is important to anticipate: Check and adjust the pressure of the inflatable compartments (inflating or deflating according to the case) according to the temperature variations (especially when there is a considerable difference in temperature between morning and evening in particularly hot areas) and make sure that the pressure remains within the recommended pressure range (from 220 to 270 MB / green sector).

BUOYANCY CHAMBER – Pressure

RISK OF PRESSURE LOSS

EXAMPLE: Your boat is exposed to direct sunlight on the beach (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 REINFLATE 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 to 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 chambers), doubling the initial pressure (480 Mb). YOU WILL THEN NEED TO DEFLATE the boat to return to the recommended pressure.

IF YOUR BOAT IS OVERINFLATED, THERE WILL BE UNDUE PRESSURE ON THE INFLATABLE STRUCTURE MAY RUPTURE IT.
IN CASE OF OVERPRESSURE

PROPULSION SYSTEM
Complies with Z Marine’s recommendations and with the engine manufacturer’s recommendations. For optimum use of your boat, seek advice from your dealer.
