The new North Sonar series features a fully modular, aluminum framed system, with three carbon wing sizes. Intelligently engineered, the Sonar system has smart and easy assembly on a single hex head bolt size. The aluminum mast and fuselage system also have a solid connection point North calls, Geolock. This ensures more efficient transfer of load into the mast form the fuselage making the whole set up more reactive to rider input. The Sonar 850 is the more kite specific all around freeride wing in the size range and with less drag it offers impressive control and smooth carving at the full range of speed. The 850 was one of the fastest in the entire test with the ability to stay controlled at higher straight line speed and also initiate and complete tight radius turns and smooth powdery carves. The 850 was also surprisingly easy to get up and going even in the lighter winds where larger foils work more efficiently. Despite being slightly smaller than the surf style wings the 850’s ability to pump and pop up on a plane, and keep afloat at slower paces was surprisingly impressive. The Sonar has a shorter length fuselage which seems to lend to its ability to drive some tighter radius turns. Great foil as skills advance and foil riders become comfortable with more speed.
