TRITON

See the world's deepest diving passenger submarine

One of the leading names in superyacht-specific submersibles, Triton returns for 2015 with the snappily named 36000/3 – better known as the world’s deepest diving passenger submarine. Designed to support scientific and commercial work, as well as marine tourism, the 36000/3 can dive to depths of an incredible 11,000 metres in two hours and offers seating for two plus a pilot. The sub is just 4.1 metres in length and weighs in at 9000kg so, if you have room in your garage, this is the toy for extreme exploration.
