We all love skating and snowboarding, donât we? How many times have you felt the need for that extra assistance to move forward? How about a hand-held land sail that uses wind to propel your skate or snowboard? David Guillot has done just that with some duct tape, plastic tarp and some fiberglass poles. Though David is selling them at $59.99 each, he has been kind enough to post a guide as to how to make it on your own. This DIY hand-held land sail could make your skating adventure more adrenalin packed. The video on YouTube can also prove to be useful.
