Inflatable kayaks
A special type of kayak that can inflate from a very small size, This type of Kayak is also referred to as a "ducky". Inflatable kayaks are great for rafting and can usually be transported by hand using a carry bag. Inflatable Kayaks are made up of hypalon (a kind of neoprene), pvc, or polyurethane coated cloth. They can be inflated with any type of air producing device, hand pumps, air tanks etc. Multiple compartments in all but the least expensive increase safety. They generally use low pressure air, almost always below 3 psi.
Until recently, inflatable kayaks have been non-rigid boats, essentially pointed rafts, and best suited for use on rivers and calm water. However, recently some manufacturers have combined folding kayak design principles (notably the use of an internal frame) with "Sit-on-top kayak" (see above) overall design using multiple inflatable sections to produce a seaworthy inflatable sea kayak.
Besides being portable, inflatable kayaks generally are stable with a small turning radius and are easy to master, but they take more effort to paddle and are slower than traditional kayaks. This type of Kayak is ideal for beginners and those who are less experienced on the river.
