We can offer electric submarines for sale or lease, diesel electric submarines for sale or luxury personal submarines for sale or lease. Designed & built specifically for the person who has everything & wants something a little different. We have a range of different sizes and models to choose from, both new & used. You can choose from a shallow water or deep sea submarine. Shallow water models like the SDE-8 & the SDE-16 luxury or commercial models, typically operate between 0 – 100m depth & the Deep Sea models from 0 – 3000m water depth.
We also can offer human powered submarines for sale & wet submarines for sale. A ‘Wet Submarine’ is a submarine in which the cockpit of the submarine is designed to flood during diving. The pilot is actually a SCUBA diver. He sits inside a submarine cockpit, wearing a miniaturized version of SCUBA gear to breath. The ‘Wet Submarine’ extends the range a SCUBA diver can explore and adds an exciting new dimension to diving. These ‘Wet Submarines’ can be battery powered or even human (pedal) powered.
We also offer professional maintenance, crewing, refit and manufacturing services to Submarine & ROV system owners, operators & prospective owners.

Wet Subs & Fun Subs
SportSub Nemo is an entry level, 3 person, swim in, Wet Submarine. Rated to 40m (130′), Its Funky appearance belies a sophisticated design. It provides a roomy cockpit and generous viewports. Incorporates fly by wire joystick, Electronic Bouyancy Control & Electrical Systems Monitor. Optional extras include Thru Water Communications, Expanded Air Supply & Lights. Its buoyancy distribution ensures that it always remains upright & it will happily sit on the seabed, while the passengers take an outside excursion. A commercial Wet Submarine version ‘ResortSub’ is available with increased battery capacity & more comprehensive instrumentation. Pilot / Operator training courses are available. SCUBA certification is required. A RIB Inflatable deployment system is also available for extended range.
This Mini- Wet Submarine is a compact ride-on craft with a depth rating of 12 metres. Weighing less than 100kg, it is designed to be affordable & simple to use, so you can explore the sub-surface environment with only minimal training and without the need to wear a SCUBA tank. Instead, you sit astride the seat as you might on a regular scooter and place your head inside the aerated helmet. The helmet is fed directly from an onboard tank, creating an ‘air bubble’ so you can breathe freely, without the need for a mouthpiece.
Your depth is controlled by inflating and deflating a bladder attached to the scuba tank and your steering is managed by means of a simple hand-operated rudder. Propulsion comes from a 750w DC motor, which is powered by a single 12V, 50AH battery – and while a five or six hour charge will give you 60 to 80 minutes of operating time, the basic package includes a spare battery so you can get a more extended session on a single trip. Prices starting at £12,000 for the one-man Wet Submarine model. Multiple (side by side) seat Wet Submarine models available also.
