“A submarine always comes up, we have to force it down,” said Philippe Epelbaum, the founder of the company Subspirit, which presented the latest attraction in Lucerne’s lake basin at the Verkehrshaus in Lucerne on Tuesday. The P-63 is therefore the only submarine in Switzerland with a permit for passenger journeys.
The gray, 6.5-ton capsule on October 16, from the end of the year passengers can dive up to 100 meters deep into Lake Lucerne by submarine. There is space in the 5.5 meter long and 2.5 meter wide vehicle for three passengers and a pilot.
The P-63 was built on Lake Constance in 1987 and was mainly used for inspections and underwater work used, for example on dam walls. Then the boat came to Hergiswil professional diver Franz Hattan, who wanted to offer passenger trips with it in 2018, but then sold it to the company von Epelbaum for around 100,000 francs.
Easier to use
When asked by the Keystone-SDA news agency, Hattan said that the submarine was not suitable for passengers and that there was a comfort problem . Eliminating this would have exceeded his financial means.

Epelbaum said that one has several hundred thousand francs invested in the renovation. A new submarine, on the other hand, would have cost several million francs, would be less compact and not as easy to handle as the P-63.
This has four battery-powered electric motors, one of which is for diving is responsible. The devices on board can also be controlled mechanically, brown wooden levers inside the submarine are responsible for inflating the ballast tank.
«Dead man» and fire extinguisher
Epelbaum explained the various safety precautions in detail. The submarine has a so-called “dead man”, a button that the pilot has to press at regular intervals, otherwise the lift is automatically initiated.
In addition to the lead weights, which depend on Weight of the passengers come on board, there are mechanically released weights, a notboye that connects to the surface boat that is with every dive, and also a fire extinguisher.
The survival time Board is 96 hours, in an emergency there is a dry toilet, the Nidwalden Shipping Office has approved the submarine for a depth of up to 300 meters. There is constant pressure behind the five centimeter thick steel shell, unlike conventional diving, no decompensation is necessary.
Weightless feeling
Unless it’s fascinating to dive to 100 meters without equipment within a few minutes, said Ueli Frey, one of the pilots. It is just as quick to get back up there. There is a kind of weightless feeling.
Two shipwrecks are approached while driving. But it’s not just nice what you see while diving, said Epelbaum. “There is also rubbish.”
The exclusive trip in the submarine is not cheap. It costs 490 francs per person. For the time being, it is planned to offer the trips three days a week, later the offer will be extended to other waters. In addition, Epelbaum wants to make the submarine available for technical journeys, for example for search and rescue missions. (sda)
