A starter kit, Brown says, runs $2,500 to $3,000. That includes four items: kite, board, bar (to steer the kite) and harness. Each can be customized, with different kites and boards for different styles of play. The Cabrinha Radar kite, for instance, is a good beginner kite because it relaunches easily when you’ve crashed into the drink. The Switchblade is for cruising along or trying some tricks, while the Drifter has a slack-line component for surfing.
