The Aqua Marina Steam-312 kayak is a one-person inflatable touring kayak built for people who want the feel of a hard shell boat without the storage hassle. It measures 312cm long and 90cm wide and weighs just 11.52kg. Made from super-tough reinforced PVC, it holds its shape well once inflated and can carry a payload of up to 95kg.
Underneath sits a rigid drop-stitch double wall fabric floor at 7cm thick, paired with an inflatable V-shape keel that helps it track straight rather than wander off course. A superfast 1+8 self-bailing drain system clears water fast during longer paddles or mild river runs.
The high-back seat has a spongy cushion and storage pockets and a foam footrest adds comfort on longer trips. Two removable fins with a central lock pin improve tracking further. It packs into a zip carry backpack with a 20L drybag included, plus a hand pump to get you started.
Most reviewers report inflation times of around 10 minutes using the included hand pump. The kayak requires two pressure levels: 1.45 PSI for the air chambers and 4.35 PSI for the drop-stitch floor. Once inflated it holds its shape well and feels rigid similar to a hard shell kayak.
No. The package includes a 16 inch hand pump, a high-back seat, two removable fins, a zip carry backpack and a 20L drybag. A paddle is not part of the standard package, so you will need to buy one separately.
The Steam-312 has a maximum payload of 95kg. This includes the paddler and any gear carried on board such as the drybag. Staying within this limit keeps the kayak sitting correctly in the water and maintains stability.
It works well on both. The self-bailing drain system is designed for long-distance touring and mild river running. Reviewers have used it on lakes such as Bala and rivers like the Dee, reporting good handling against wind and current.
This is a mixed point in reviews. Some paddlers found the foam footrest positioned too close to the seat, making leg position quite upright, particularly for taller users. One reviewer at 5'10" modified the footrest straps for extra length. Shorter paddlers also noted it felt somewhat unnecessary for their height.
Reviewers with hard shell kayak experience describe the Steam-312 as feeling rigid and stable once inflated, thanks to the reinforced PVC and drop-stitch floor. It doesn't fully replace a hard shell in terms of low sides, but it performs well for tracking, speed and manoeuvrability.
The kayak packs into a zip carry backpack that also holds the pump, seat and fins. This makes storage at home simple and means it can travel in a car boot without needing roof racks.
One reviewer reported the internal white plastic part of the pump cracked after light use and they had to borrow a pump to try the kayak. If you experience this, it's worth contacting the seller directly for a replacement under the 1 year warranty.
