Surfing can be annoying sometimes. Crowds, junk waves, and that guy sitting way out back on a longboard catching every set wave. Melted wax, chaffed nipples, and urchins in your feet. Angry locals, fin cuts, and onshore wind. But like anything else, there is always another option. For Jonas Lengwiler and Ronny Bollhalder, the answer to all that is to simply leave the ocean, leave the crowds, leave the surfboards, and embrace the wind. Instead, they hooked their waists to a couple of sails and their feet to a couple of foils.
