INSTRUCTION FOR ASSEMBLING
AND DISASSEMBLING
Pump Set Up And Inflation
B
A
C
1. Open the valve cap by twisting counter-clockwise. Ensure the valve is
clear from debris, sand, or dirt before releasing.
2. Push valve button in and turn counter-clockwise 90 degrees so it pops up
and is in the “OUT” position.
3. Insert the pump hose and twist it 45 degree clockwise to lock in place.
Inflate until you reach the required pressure.
Connect the pump hose to the
gauge housing and secure it tightly.
①①
UNFOLD THE BOAT
Clear a clean and flat space
that is free of any sharp
objects and unroll the boat
hull so that it is laid out flat.

6
Over inflation will void your warranty. 12PSI
minimum for proper inflatable deck floor
operation and 15PSI maximum.
D
1. Use DOUBLE ACTION mode by closing the air-tap to pump the boat
hull up to 0.25 bar/ 3.62 psi, and the deck floor up to 0.5 bar/ 7 psi.
2. Switch to SINGLE ACTION position by opening the air-tap to pump the
deck floor up to 1 bar/ 15 psi.
Inflate Faster With Less Effort
•Use full range of the pump cylinder
while keeping your arms extended.
•Bend your knees and use the body
weight.
DOUBLE
ACTION
SINGLE
ACTION
• Electric Pumps can be used to inflate boat up to 80-90%. However, the
remaining pressure required should be achieved by using the hand
pump to avoid over-inflation.
• Do not use air compressors as this voids warranty of boat.
• Before long trips, ensure the boat has been inflated and has maintained
pressure for a minimum of 24 hours.
PRECAUTION & TIPS
The pump can be switched between double action mode and single
action mode.

INFLATE THE BOAT
1. Inflate the tube chambers until the surface is free of wrinkles. By partially
inflating the boat, the floor and the bench seat will be easier to install.
2. Place the DWF air deck floor inside of the boat with the air valve facing up.
3. Start to install the wooden bench seat. Slide the bench seat into the position by
inserting the flaps on both chambers of the boat into notches on the seat board.
Please note the second bench seat is sold separately.
4. With the floor installed and the seat in place, you are now ready to fully inflate
the floor up to the maximum air pressure (1 bar/ 15 psi). Then, fully inflate the
tube chambers up to the maximum air pressure (0.25 bar/ 3.62 psi).

5. Insert the plug into the drain valve beneath the transom.
IMPORTANT!
Make sure that the drain valve is always in the closed position as shown in picture
(5) while on the water. When you are motoring is the only time that the drain valve
can be in the opened position.
NOTES: Always check the inflation pressure before using the boat. Air temperature
and weather conditions do affect the internal air pressure of inflatable products. In
cold weather the product will lose some pressure due to the fact that the air will
contract. If this occurs, you may want to add a little air to the product. However, in
hot weather, the air will expand. In this case, you must let some air out to protect
the product from overpressure.
• Only use Aqua Marina® approved inflation pumps.
• Under and over-inflation will result in safety hazards.
• Never stand on or rest objects on the boat during inflation.
• Never open the cap of air valve while the boat is in use.
• Be sure the valve is tightly closed before using the boat.
Before deflation, please keep in mind that you should not fully deflate one
chamber while other chambers remain fully inflated as this can cause damage to
the bulkheads of your boat.
1. Clear any water or debris out of the valve areas.
2. HIGH PRESSURE VALVE
Open the valve cap first. Slowly press down on the valve stem to start letting air
out of the boat. There will be an initial burst of air, but that will slow down very
quickly. Once the air flow has slowed down, press the valve stem all the way
down and turn it clockwise to lock it into the “OPEN” position.
3. Open all air valves including the tube chambers and the DWF air deck floor.
Release around 50-75% of the air from each chamber before fully deflating.
Excess air can be pushed out as you roll up the boat.

1. Remove all the accessories from the boat: oars, wooden seat and the DWF air
deck floor.
NOTE: Remember to remove the DWF air deck floor before folding.
2. Fold the end of the tube chambers towards the transom.
3. Roll the boat towards the bow, pushing out any remaining air as you go. Then
have one fold from the bow and tuck the bow neatly underneath.
4. For the DWF air deck floor, make the first fold from the front. Continue folding
towards the valves tightly, pushing out any remaining air as you go.
5. The boat storage bag is designed to allow you to get your boat into the bag as
easily as possible with minimal folds.

2. OUTBOARD MOTOR INSTALLATION
After the boat is fully inflated and well assembled, attach your outboard motor onto the
Engine Mount at the center of the transom.
NOTE:
•Ensure the motor is always fixed on the transom.
• Read the instruction manual of the outboard motor for correct installation and operation.
WARNING:
Overpowering a boat can result in serious injury, death or boat damage. Do not exceed the
maximum motor power.
ACCESSORY ASSEMBLY
1) Join the two shafts of the oars by snapping them together.
2) There are pre-drilled holes in the middle of the oars so you can slide it over the oar
holder and then secure the oar in place by using the rotation oarlock.
NOTE: When the oars are not in use, leave the oars in the oar holders to avoid
damage and loss.

The boat is made of the high quality materials and complies with ISO 6185 standards.
Altering the construction of the boat will endanger your own safety, safety of the
occupants and void the limited warranty!
There is very little that you have to do to keep your boat in good condition for many
years.
• When landing on the shore, carry the boat. Do not tow it on the sand or ground as
damage may occur.
• If you use the towing D-ring to tow the boat, go slowly to avoid over-towing as
damage may occur.
• Clean your boat after a trip to prevent damage from sand, salt water or sun exposure.
Most dirt can be removed with a garden hose, a sponge and mild soap.
• Make sure the boat is completely dry before storing, and remove any excess moisture
that could cause unsightly mildew. Use as few cleaning agents as possible, do not
discharge waste agents into water, and clean your boat preferably on land.
• Choose a cool and dry spot to store the boat. Ensure protection against rodents and
other vermin, as they feed on the fabric of the boat.
• The boat may be stored inflated, but do not place any heavy or sharp objects on it.
Hanging the boat is not recommended.
• If you’re planning to leave your boat outside, make sure to keep it raised up off the
ground. It is also a good idea to keep it covered so that it is not directly exposed to
berries, leaves, rain, sunlight and other elements. Boats that are left in water should
be emptied from time to time.
• Store the product and accessories in a dry place, with temperature controlled
between 32 degrees Fahrenheit (0 degrees Celsius) and 104 degrees Fahrenheit (40
degrees Celsius).

AIR LEAK DETECTION
If your boat appears a bit soft, it might not be because of a leak. If the boat was inflated
late in the day with 32°C (90°F) air, that air might cool down to 25°C (77°F) overnight.
The cooler air exerts less pressure on the hull, so it could appear soft the next morning.
If there has been no temperature variation, you need to start looking for a leak:
• Take a good look at your boat from just a few feet away. Flip it over and closely check
over the outside. Any large leaks should be clearly visible.
• If you have an idea where your leak is, use a mix of dishwashing liquid and water in a
spray bottle, and spray over the suspicious areas. Any leak will produce bubbles that
will pinpoint the location of the leak.
• Check valves for leak, if necessary, spray soapy water around the valve and the valve
base.
LEAK DETECTION AND REPAIR
SMALL REPAIRS
1. Thoroughly clean and dry the damaged area. Completely deflate the product.
2. Cut a portion of the patch to cover the puncture and allow an additional 1/4” on
all sides. Always cut a round patch, never leave square corners.
3. Be sure the repair area is completely dry.
4. Apply generous coat glue to the vinyl repair patch and to the product.
5. Allow the glue to dry for 2 to 3 minutes, or until the glue becomes tacky.
6. Apply the patch to the product, using your thumb or finger; apply even pressure
across the entire surface of the patch. Make sure the edges of the patch are
pressed down along the entire diameter.
7. Allow the product to dry for at least 12 hours before inflating and using.
If there are large tears/cracks, please bring the water craft or any essential equipment
part into a professional repair shop for appropriate repair or replacement.
Inadvertent punctures can be repaired using included vinyl repair patch and vinyl glue.
You can also purchase additional PVC or silicon based glue for repairing camping mats,
tents or shoes from your local market to patch your boat. Please refer to the instruction
of the glue for patching.
