Kayaking

Although kayaking is a popular activity, not everyone has the money, storage space or transport capabilities required for one of the boats. That's where the Kayakomat comes in, as it's an onsite, internet-bookable kayak-rental vending machine.

Touring kayaks are typically made of plastic, composites or sometimes wood, but unlike canoes, almost never aluminum. That didn't faze Brennen Kunka, however, who recently built his own all-aluminum kayak from the ground up – and it's awesome!

Although one of the big appeals of paddleboards and kayaks is the fact that they are human-powered, there are some scenarios in which a motor could help. The HydroJet was designed with that fact in mind, as it can be mounted on existing watercraft.

When we last heard about Belgian startup Onak, it was debuting an improved version of its origami-style folding canoe. Now, Onak is back with a considerably smaller and less costly boat, called the Bato.

Ever since Oru introduced its first origami-style folding kayak back in 2012, other brands have come out with boats that were claimed to be lighter and more compact. Oru has now addressed that competition, with its sub-$700 18-lb (8 kg) Lake kayak.

Kayaks typically aren't something that you can store in a closet or carry in a backpack. That's why we've been seeing an increasing number of folding kayaks, and the Pontos is one of the lightest, smallest-folding models we've come across so far.

Stand-up paddle boards certainly can be fun, but kayaks are generally a faster, more efficient means of getting around. Watercraft company Bote has now combined the best features of both, in its redesigned Rackham Aero paddle board.

Although most kayakers like their boats because they're human-powered, a motor could still help out in some scenarios. And while there are already pre-motorized kayaks, the PacMotor system adds two motors to an existing boat.

While we have seen motorized kayaks before, most of them simply utilize an outboard motor, or they don't have the form factor of a true kayak. The Czech-made eMogi, however, looks fairly conventional, and has its own integrated electric motor.

While some people like the idea of kayaking, they may be put off by how cumbersome the boats are to transport, and how tippy they can be. The Super Kayak – currently on Kickstarter – is made to address both concerns.

If you want a kayak (that isn't inflatable), you typically also need a car with a suitable roof rack. German product designer Daniel Schult has come with an alternative, however, in the form of a folding kayak that can be carried like a backpack.

When you're out sea kayaking, it's likely that you might stop for a break on a beach. The Tupik Kayaker Fly provides shelter from the sun when you do, by quickly attaching to two kayaks and their paddles.
