Wakeboard Ballast Bags included (per the seller) The 2005 Tige 21i is a direct-drive wakeboard/ski boat. This boat is wide and roomy probably could be one of the roomiest 21-foot direct-drive. This 21i optimizes passenger flow and storage. The 2005 Tige has a deeper freeboard. Equal parts ski and wakeboard boat, the 21i is exceptional at both, thanks to the unique ConvexV and TAPS2 technology. The Skybox seating allows quick reversal of the rear seat to maximize passenger viewing and weight distribution in wakeboard configuration.
