The Iguana 29 Ground Boat is a unique vessel that sports a pair of retractable all-terrain caterpillar tracks to let it traverse terra firma as well as the open seas, eliminating the need for marinas, docks, and other vestments of traditional watercraft. Of course, it's also designed for discerning owners, and as such offers open-water speeds of up to 35 knots, a teak floor, and room for up to 10.
