• Sheltered estuaries
• Appropriate sheltered coastal conditions
• Longer recreational trips within the paddlers' experience
• Carrying equipment within the stated payload

Which STEAM Model Should I Choose?

• The kayak will normally be used by one paddler.
• A 110kg maximum payload is sufficient.
• A lighter 9.8kg hull is preferred.
• Compact storage and transport are priorities.
• The narrower 81cm solo configuration is suitable.
• One seat is required.

Choose the STEAM 412 when:

• The kayak must carry two paddlers.
• A maximum payload of 180kg is required.

Paddles are not included with any of the three variants.

What Is Seamless-Tube Construction?

The side-tube seams are joined using high-frequency welding. This creates a bonded seam designed to support the inflated hull shape, improve durability and reduce reliance on exposed glued seams.

What Is the 7cm Drop-Stitch Floor?

The STEAM uses a removable high-pressure floor manufactured with drop-stitch construction. Internal fibres connect the upper and lower floor surfaces, allowing the floor to remain comparatively flat when inflated.

• Increased rigidity beneath the paddlers
• Reduced floor flex
• A firmer seating and foot-bracing surface
• Improved transfer of paddle effort
• Better stability when entering and leaving
• More responsive handling
• Easier removal for cleaning and drying

Inflate the floor only to the pressure stated on the kayak and in the current Aqua Marina instructions.

What Are the Recessed Foot Braces Used For?

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

• Support an upright seating position
• Improve paddle-stroke efficiency
• Reduce movement in the seat
• Improve control during turns
• Reduce fatigue on longer trips
• Stabilise the paddler in moving water

What Is V-Cone Protection?

Hard V-cone sections are fitted at the bow and stern.

• Protect the most exposed ends of the kayak
• Reduce abrasion during launching and recovery
• Provide additional resistance to minor knocks
• Help the bow and stern retain their shape
• Protect the inflatable structure during normal use

The V-cones improve protection but do not make the kayak collision-proof.

What Is the Deck Shield?

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

• 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 layout

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

How Does the Streamlined Hull Affect Performance?

• Improves straight-line tracking
• Reduces unnecessary drag
• Maintains speed between paddle strokes
• Reduces repeated corrective steering
• Improves touring efficiency
• Provides responsive handling
• Supports flat-water touring and suitable mild-river use

How Should the Fins Be Used?

• Install both fins before launching on suitable flat or deeper water.
• Slide each fin fully into its mounting box.
• Secure the fin using the supplied retaining arrangement.
• Confirm that both fins are locked before launching.
• Remove the fins before folding the kayak.
• Do not use the full-size fins where they may strike the bottom.
• Rinse the fin boxes after use in sand or salt water.

What Is the Difference Between Hull Weight and Maximum Payload?

Hull weight is the published weight of the inflatable kayak itself.

Maximum payload is the total weight carried aboard, including paddlers, clothing, seats, food, drinking water, dry bags, safety equipment and all other items.

How Should the STEAM Be Set Up?

• Unroll the kayak on a clean surface free from sharp objects.
• Inspect the hull, floor, seams and valves.
• Position the removable drop-stitch floor correctly.
• Inflate the chambers in the sequence stated in the Aqua Marina instructions.
• Use the supplied hand pump and monitor the pressure.
• Do not use an unregulated high-pressure compressor.
• Close every valve cap securely.
• Fit the required number of seats.
• Adjust the seat straps for an upright paddling position.
• Fit the removable fins where water depth permits.
• Secure suitable luggage inside the kayak.
• Check that the drain valve is correctly configured.
• Confirm that the kayak, seats, fins and equipment are secure.
• Obtain the correct paddle or paddles separately.

How Should the Kayak Be Loaded?

• Keep heavier equipment low and close to the centre.
• Distribute paddlers and luggage evenly.
• Do not overload the bow or stern.
• Secure all loose equipment.
• Keep the cockpit clear enough for safe entry and exit.
• Do not obstruct the drain valve.
• Keep sharp items inside protective bags or containers.
• Include all carried equipment in the payload calculation.

Safety and Use

• Wear a correctly fitted buoyancy aid or personal flotation device.
• Check weather, wind, current, tide and water conditions.
• Remain within the passenger and payload limits.
• Use the kayak only in conditions appropriate to the paddlers' ability.
• Keep children and inexperienced users under suitable supervision.
• Tell someone the planned route and expected return time.
• Carry suitable communication and rescue equipment.
• Keep clear of powered vessels and marked navigation channels.
• Do not paddle while affected by alcohol or drugs.
• Do not rely on the kayak as a life-saving device.
• Follow local waterway, 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.
• Remove the drop-stitch floor where required for cleaning.
• Allow the hull, floor and accessories to dry completely.
• Inspect the welded seams for abrasion or damage.
• Check the chambers and valves for leakage.
• Inspect the V-cones for impact damage.
• Remove the fins before folding.
• Release the air fully before packing.
• Avoid repeatedly forming sharp folds in the same area.
• Store the kayak in its backpack in a cool, dry location.
• Protect it from prolonged sunlight, frost and excessive heat.
