The Iguana 29 is a new take on amphibious vehicles, using retractable caterpillar tracks to deliver surefooted drive across extreme terrain at up to 8 km/h while on water it is quick to plane and has 35 knot speed. Most impressive of all is that the hybrid version of the Iguana can run in electric only mode in nature's most delicate areas. The Iguana 29 and its retractable caterpillar design looks to address an important need for boats capable of entering and exiting the water in complete independence. The Iguana has enough carrying capacity to be very versatile and could serve as tender, to land anywhere, as a leisure craft offering freedom from marinas, berths and other constraints, or for transporting goods and equipment.
