Is the Blocart a go-cart with a sail? Or is it a sailboat with wheels? The answer might not be entirely clear, but whatever it is, the Blokart is a heck of a lot of fun. The brainchild of Paul Beckett, a Kiwi with an affinity for outdoor adventures, the three-wheeled, single-sailed Blokart turns any stretch of sand, vacant parking lot, or even tennis court into an earthen ocean. A single accelerator cable allows novice riders to control their speed on even the gustiest days, though adventurous riders have an eye on the current Blokart land-speed record of 60 mph. $2,495-$3,295.
