Dublin, Ireland – Once-in-a lifetime trip for Belgian winner in world’s first Guinness Deep Sea Bar. In a global first, a lucky Belgian competition winner has travelled into the depths of the black stuff in the first ever Guinness Deep Sea Bar. Evelyne Gridelet, 30, of Seraing, Belgium, won the incredible trip in the futuristic custom-built Guinness Underwater Bar as part of the Guinness Experiences competition, held during the global Guinness 250 celebrations.

Along with her husband, Arnaud Splendore and sister, Virginie Gridelet, Evelyne was flown to Sweden for an unforgettable four-day trip to explore the remote islands of the Stockholm Archipelago. Set against a winter wonderland, the highlight of their adventure, which took place during the last week of January 2010, was travelling to the bottom of the Baltic Sea in the GUINNESS DEEP SEA BAR that was modified exclusively for the trip by Silvercrest Submarines.

Evelyne said, “This has been an unbelievable trip of a lifetime! Winning the Guinness Sea Experience has given me the chance to do something totally unique and unforgettable, and I think I’m the first person ever to enjoy a cold glass of Guinness on the ocean floor!”

To enter the Deep Sea Bar, Evelyne and her guests had to face a snow blizzard and temperatures of minus 15°C, as they walked out across the frozen surface of the Baltic Sea. Earlier in the day an icebreaker cleared a path for the voyage under the sea. Once inside the Deep Sea Bar, the winners dived to the bottom of the sea experiencing spectacular views of the underwater landscape below the ice-cap while enjoying a glass of Guinness in this most unique of locations.

The Guinness Sea Experience was one of three remarkable prizes offered as part of the first global promotion for Guinness. These remarkable experiences were created as part of the worldwide celebrations to mark Arthur’s Day, the anniversary of 250 years since Arthur Guinness signed the 9,000-year lease on the St. James’s Gate Brewery in Dublin.

This affordable two-man Underwater Scooter is the latest high tech submersible to join the marine leisure market. Ideal for super-yacht owners, diving enthusiasts, tourist resort operators, and dive operators. This scooter is perfectly suited for couples to explore the underwater world in safety and comfort.

The scooter helmet is nicely integrated into the scooters body. Each rider’s head goes inside an air chamber within the helmet, which is constantly supplied with air from scuba tanks lasting seventy minutes, which are attached to the front body of the scooter. The helmet features a flat fog resistant glass, 99% distortion free giving a clear underwater view.

These scooters are sleek and lightweight (160 lbs.).

Each scooter is powered by two electric motors, one for forward movement and another for vertical movement, providing precise control, manoeuvrability and safety. The controls operate like your typical motorbike. Just turn the handlebars for direction and push the batons for speed and depth. Pressure and depth gauges are provided on the control bar.

With a maximum speed of 3 mph and an operating depth of up to 12 meters, riders have access to shallow reefs and caves. The motors run by a rechargeable battery lasting up to 2.5 hours.

Novices can master the controls in the training course that can be completed in just a few minutes. Those who are not strong swimmers or who have minor disabilities can still ride the bike and can wear glasses or contact lenses without difficulty.

A line attached to a marker buoy keeps the scooter safely tethered to the world above.

This underwater scooter is a one person, 2 knot, submersible designed to enable certified and non-certified divers to cruse effortlessly underwater. This unique vehicle combines a bubble helmet, seat, tank and thruster inside a rotationally molded, impact resistance, polyethylene body.

The operator sits in a comfortable upright position with their head in a bubble of air. A button on the steering wheel operates the thruster under the seat. Simply pushing the button and steering enables the operator to drive around in comfort and safety underwater.

Cruise effortlessly underwater without the need to wear cumbersome dive equipment. Simple submerge underwater, put your head into the air bubble and swing your leg over the seat. The standard scuba cylinder delivers continuous fresh air into the bubble for over one hour. Depth is controlled by inflating or deflating the internal air bladder (the same as scuba diving). A surface float is used to set the maximum dive depth and protect the reef.

The 12volt thruster, mounted inside a protective cowling, operates for over one hour per charge. The interchangeable scuba cylinder, and 60ah gel cell battery, enable one-hour dive times, and five-minute change-over rates.

These are exciting, fun machines on which anyone aged 10 and upwards can experience the underwater world. You do not need to be able to swim or dive to operate the underwater scooter.

The first tourist operation was set up with ten units, offering sixty people per day a thirty-minute underwater experience for $99 per person. In St Thomas, Carnival Cruiseline offers over 80 people per day a twenty-minute ride for $99 each. In Nassau rides sell for $110 each.

Most tourist operations start with ten scooters and add additional units as needed. Two rides per hour per unit gives the customer a memorable experience, and enough time for the operator to change over the HP air cylinder and battery. Secondary batteries and air cylinders are charged simultaneously.

Additional revenue can be generated through selling camera pictures, videos, T-shirts and merchandise. A custom built vessel for a scooter operation carrying 10 scooters, 20 passengers and 4 crew, is available.

Training programmes for operators, and assistance to set up your new tourist operation on a boat, pontoon or beach, is available on request.

This unique submersible combines a bubble helmet, seat, tank and thruster, inside a molded, impact resistance GRP body. The operator and passenger sit in a comfortable upright position with their heads in a bubble of air. The ‘air bubble’ is fed directly from the air tank creating a dry environment, allowing the riders to breathe freely without the need for a mouth piece. The observation ‘hood’ also means there is no need to wear a scuba mask or any form of restrictive head gear.

By adding additional, simple to install, ballast modules (supplied with the scooter as standard) the unit can also be operated as a single rider unit.

No diving experience is required, everyone can ride the scooters underwater, sitting inside their own bubble of air. Operated by an electric motor. With a maximum advised depth of 25ft (8m), riders can explore shallow reefs, and watch the colourful fish life around them. The controls operate like a typical EV motorbike.
