The Swing uses an efficient "tubeless" system. The hulls are made of rip-stop polyester fabric, rubber-coated on the interior for air-retention, and Teflon®-treated on the outside for water repellency and stain resistance. The air-holding seams are vulcanized and permanently bonded (similar to the way in which tires are vulcanized). Each chamber is individually tested at the factory for air retention. The Swing 'tubeless' construction parallels what tire manufacturers went to decades ago - it is inherently light, but it also inflates to a higher pressure than competing bladder kayaks (3-psi vs 2-psi). The higher pressure means that the Swings are stiffer in rough water and have snappier paddling performance. Other decked inflatable kayaks are built using an unreinforced vinyl bladder inside a zip-on skin. This technique results in a heavier boat...and the potential for water to get trapped making it difficult to dry and pack away.
Swing decks are urethane-coated with zippered access for gear storage and cleaning ease. The decks shed water quickly and easily. The deck support system uses aluminum arches fore and aft of the cockpit openings. These arches are set crosswise and provide a deck shape and structure. The arches contribute to the stiffness of the Swing for paddling in rough water. These arches can be removed easily for a compact folded package, or left in the kayak for a slightly larger folded size. The decks have fore-and-aft zippers for ease of gear access and cleaning the boat. The aft zippered deck opens completely in two flaps for full access. Each deck is provided with gear bungees.
Polyvinyl Chloride (PVC) is increasingly being recognized as a material of significant environmental concern. Environmentally conscious companies such as L.L. Bean have a PVC-free policy on the products they sell. The Swing is free of PVC. Each kayak is divided into three separate air chambers for safety. The valves are sophisticated 'bayonet' style units set flush with the fabric surface. A pressure relief valve is installed in the kayak floor chamber to relieve possible overpressure. Setup time with a manual pump is about 5 minutes.
