Pro windsurfer Alan Cadiz founded HST in 1985, and as the name suggests, it specializes in teaching windsurfing and kitesurfing, along with paddleboarding. The the school's five-level windsurfing program is taught one-on-one or in small classes, with two to three students per instructor. All students must know how to swim, and children must be at least six years old. Rates for beginner classes (levels one and two) include all equipment. Lessons take place at a white-sand beach in Kanaha Beach Park, within walking distance of Kahului Airport. Instructors are available to teach at alternative locations, though a two-hour private lesson is required to book.
