What Is the Aqua Marina HALVE Used For?

The HALVE is designed for paddlers who prioritise low carrying weight, compact storage and efficient recreational performance.

• Solo recreational paddling
• Tandem day trips
• Calm lakes and reservoirs
• Canals and inland waterways
• Calm or gently flowing rivers
• Sheltered estuaries
• Suitable sheltered coastal paddling
• Road trips and camping holidays
• Weekend paddling trips
• Longer recreational journeys within the paddlers' experience
• Users without space to store or transport a rigid kayak

The streamlined profile is intended to provide efficient glide and tracking while retaining the portability of a packable inflatable kayak.

Which HALVE Model Should I Choose?

Choose the HALVE 335 when:

• The kayak will normally be used by one person.
• A maximum payload of 120kg is sufficient.
• The lowest possible carrying weight is a priority.
• A 6.9kg hull is easier to transport to the water.
• Compact vehicle and home storage are important.
• The narrower 81cm solo configuration is preferred.
• One seat is required.

Choose the HALVE 398 when:

• Two paddlers need to travel together.
• A maximum payload of 180kg is required.
• Additional cockpit and luggage space are needed.
• The wider 98cm configuration is preferred.
• The kayak may be used for shared day trips or touring.
• Two seats are required.
• The additional length and 9kg hull weight remain practical for transport.

Maximum payload includes every paddler and all clothing, drinking water, dry bags, safety equipment and other cargo carried aboard.

What Is PACKAYAK™ Construction?

PACKAYAK™ describes the HALVE's emphasis on low weight and compact packed dimensions.

After deflation, the kayak folds into the supplied TPU backpack, allowing it to be transported without a roof rack or large rigid-kayak storage area.

• Suitable for car boots
• Suitable for campervans and motorhomes
• Compact storage in apartments and smaller homes
• Portable on public transport
• Practical for campsites and road trips
• Easier to carry short distances to launch points

What Is TPU Construction?

TPU is a flexible thermoplastic polyurethane material used to create a lightweight, foldable inflatable structure.

• Lower carrying weight
• Compact folding
• Smaller packed dimensions
• Durable welded inflatable chambers
• Responsive hull shape when correctly inflated
• Easier transport and storage

TPU remains vulnerable to puncture, abrasion and excessive heat. Keep the kayak clear of hooks, glass, sharp rocks, exposed metal and rough concrete.

What Is the Reinforced DWF Floor?

The HALVE uses a reinforced DWF floor to provide a firmer base beneath the paddler or paddlers.

• Improved rigidity
• Reduced flex beneath the seats
• More efficient transfer of paddle effort
• Increased stability when entering or leaving the kayak
• A flatter foot-bracing surface
• More responsive handling than a basic low-pressure floor

Inflate every section only to the pressure printed on the kayak or stated in the current Aqua Marina instructions.

How Does the Streamlined Design Affect Performance?

• Reduces unnecessary drag
• Supports straight-line tracking
• Maintains glide between paddle strokes
• Reduces repeated corrective steering
• Improves cruising efficiency
• Makes longer paddling distances less demanding
• Provides a responsive all-around feel

The removable fins further support directional tracking in suitable water depth.

What Is V-Cone Protection?

Hard V-cone sections protect the bow and stern, which are among the most exposed parts of an inflatable kayak.

• Provides additional impact protection
• Reduces abrasion during launching and recovery
• Helps the ends retain their shape
• Protects the inflatable structure from minor knocks
• Supports cleaner movement through the water

V-cone protection does not make the kayak collision-proof. Avoid dragging or striking the kayak against rocks, concrete or underwater obstacles.

What Is the Deck Shield?

The Deck Shield is a raised splash-control section around the cockpit.

• Deflects spray away from the seating area
• Reduces water flowing backwards into the cockpit
• Improves comfort on longer trips
• Helps protect equipment carried inside the kayak
• Retains the accessibility of an open-cockpit design

The Deck Shield reduces splash but does not create a sealed or watertight cockpit.

How Does the Cargo Bungee Work?

The adjustable cargo bungee provides a retention point for suitable lightweight equipment.

• Dry bags
• Spare clothing
• Drinking water
• Lightweight footwear
• Compact food containers
• Small safety equipment

Secure every item so that it cannot move, fall overboard or obstruct the paddlers.

What Are the Foot Braces Used For?

The recessed foot supports provide a stable bracing point for the paddler's feet.

• Support an upright paddling position
• Improve paddle-stroke efficiency
• Reduce movement within the seat
• Improve directional control
• Reduce fatigue during longer journeys
• Stabilise the paddler in light chop

What Is the Difference Between Hull Weight and Maximum Payload?

Hull weight is the weight of the kayak itself before adding passengers or equipment.

• HALVE 335: 6.9kg
• HALVE 398: 9kg

Maximum payload is the total permitted carried weight, including paddlers, clothing, food, water, dry bags and safety equipment.

What Is the Air-Chamber Arrangement?

Both HALVE models use a 2 + 1 air-chamber arrangement.

• Inspect every chamber for damage.
• Inflate the chambers in the specified sequence.
• Confirm that every valve cap is secure.
• Use the pressure printed on the kayak.
• Do not exceed the maximum stated pressure.
• Recheck pressure when air temperature changes significantly.
• Do not launch if any chamber is losing pressure.

How Should the HALVE Be Set Up?

• Unfold the kayak on a clean surface free from sharp objects.
• Inspect the hull, floor, seams and valves.
• Arrange the floor and chambers in their correct positions.
• Inflate each chamber in the sequence stated in the instructions.
• Use the supplied 16-inch hand pump.
• Monitor pressure carefully.
• Do not use an unregulated high-pressure compressor.
• Close every valve cap securely.
• Fit the correct number of seats.
• Adjust the seat straps for an upright paddling posture.
• Fit both removable fins where water depth permits.
• Secure equipment beneath the cargo bungee.
• Check that the drain valve is correctly configured.
• Confirm that the kayak, seats, fins and cargo are secure.

How Should the Kayak Be Loaded?

• Keep heavier equipment low and near the centre.
• Distribute passengers and cargo evenly.
• Do not overload the bow or stern.
• Secure every loose item.
• Keep the cockpit clear enough for safe entry and exit.
• Do not obstruct the drain valve.
• Protect the hull from sharp equipment.
• Include all cargo in the payload calculation.
• Do not exceed the passenger or load rating.

Safety and Use

• Wear a correctly fitted buoyancy aid or personal flotation device.
• Check the weather, wind, current, tide and water conditions.
• Use the kayak only in conditions suited to the paddlers' ability.
• Remain within the passenger and payload limits.
• Tell someone the planned route and expected return time.
• Carry appropriate communication and rescue equipment.
• Keep clear of powered vessels and navigation channels.
• Keep children and inexperienced paddlers under appropriate supervision.
• Do not paddle while affected by alcohol or drugs.
• Do not use the kayak as a life-saving appliance.
• Follow local access and navigation rules.

Care and Maintenance

• Rinse the kayak with fresh water after use in salt or dirty water.
• Remove sand, weed and debris from the cockpit and floor.
• Rinse the valves, fins, seats and pump fittings.
• Allow the kayak and accessories to dry completely.
• Inspect the TPU material for cuts, abrasion or punctures.
• Check the floor, seams and valves for leakage.
• Inspect the V-cones for impact damage.
• Remove the fins before folding.
• Release the air completely before packing.
• Avoid repeatedly creating sharp folds in the same place.
• Store the kayak in its TPU backpack.
• Keep it in a cool, dry and ventilated location.
• Protect it from prolonged sunlight, frost and excessive heat.
• Do not place heavy items on the packed kayak.
