Fancy sinking your savings into a new business venture? Then why not consider buying a nice little tourist submarine? The DeepStar sub seats 45 passengers and is cleared to dive to 100 meters. Don’t bother applying unless your cheque book has space for over 6 zeros.

‘Available as a complete system with custom Passenger Catamaran and Dry/Wet Docking Support Barge. Inspection of the submarine is available at your convenience.’
