Mini-sea trials for buyers on personal subs from U-Boat Worx at the Monaco Yacht Show are a regular feature. But now it’s time to personalize these subs more, make them good enough to take home! The Holland-based company is all set to launch a new line called ‘The C-Explorer’ to accommodate six passengers’ tops. The subs will come with underwater navigation systems, robotic arms, and remotely operated vehicles (ROVs) to control the sub. Prices for a one-seater model start at about $360,000, to $1.08 million for a five-seater model.
