The C-Quester submersibles have to be the cutest little personal submarines out there. They kinda look like a 1960’s cartoon (perhaps a yellow submarine, yellow submarine…). Designed to be used as an exploring toy for mega-yachts, these 2 and 3 person subs run on a rechargeable battery good for six hours undersea. Built by U-Boat Worx, these double-hulled submersibles can go down to 300 feet and have all the comforts of home like air conditioning. They are designed to keep the pressure stable so that when you return to the surface, there is no need to decompress. Prices start at a little over half a million dollars.
