If you're tired of dropping anchor offshore and having to take a dinghy or worse from your yacht to the beach, the Iguana Yacht may be for you. It has a tank-like continuous track system built into the ship's hull, allowing the operator to go from sea to land without scratching up the bottom of the boat.
It actually looks like it would be a cool challenge to navigate. Note that this is different than the amphibious DUKWs and LARC-V military vehicles that have tires and a steering wheel and are repurposed as Duck rides in various touristy areas:
