The Spirit Surf 1250 is the largest of the four sizes in the Duotone foil range and caters to the rider that wants to cruise strapless in light winds and have a foil that works equally as well behind a kite or in other surf, SUP or wake foil disciplines. So in addition to being an easy foil to learn with in light winds, with the right kite this a great foil system if you want to get into surf or wake. Both the Spirit 950 and 1250 have similar drive and feel, but the larger surf wing has quickly accessible lift and more pumping power at low speeds. The 1250 is actually easy to plane and is smooth and intuitive with natural front foot driving at speed. There are no jitters but it tops out much faster than the 950 with less top end speed. While the lift increases and speed decreases the acute reactivity and smooth carving nature of the 1250 never subsides. It’s also more stable at slower speeds and stays on a foil at a slightly slower pace. The Spirit Surf remains controlled and feels well balanced through the turns. Having the abiltity to stay on a foil and the added stability of the large wing makes it easy to learn transitions, ride toe side and get comfortable with kite skills and foil skills at slower speeds. The short fuselage length combined with the finely tuned wing set ups, also give the Sonar more back foot directed carving ability. Many kiters that have learned to kite on a larger surf foil will need to adapt to a foil feel that has drastically different weighting of front versus back foot. Each foil has its sweet spot and that spot can also change at different speed levels or other forces being exerted on the submerged craft under your feet.
