Readers wanting to make a real splash could do worse than this mini-submarine.

The advanced Swimmer Delivery Vehicle from Exomos can accommodate up to eight people, submerge in seconds and reach speeds of 25 knots on the surface and six knots underwater, powered by a petrol and electric propulsion system.

The manufacturers say the craft is designed “for missions requiring stealth and speed”, but are aiming the SDV at the leisure market as well, with a major stand at the Dubai Boat Show in March.

The company hope to market the submarine and other models in the range in Europe over the next two years.
