About us

The U-Boat Navigator Team are passionate about diving. With over 30 years of scuba experience and 500 dives in submersibles, we have had the privilege of exploring shipwrecks, lost treasures, and areas of natural beauty.

Now we would like to share this experience with you.

“If Jacques Cousteau were alive today, he’d have built U Boat Navigator. No other private boat in the world compares to this dedicated diving vessel. Built by divers – for divers – her two custom submarines are paired with a state-of-the-art diving center for the ultimate in underwater exploration.”

The Deep Blue Experience

The Deep Blue Experience is a new and unique twist to yacht charters. We have combined the luxury lifestyle of yacht charters with the adventure and intrigue of deep-sea diving.

Our flexible charter program means you can organise the experience that suits you best. You can choose from single day dives to weeklong charters, either staying aboard the Navigator or sailing in tandem with your own yacht.

We want to ensure you experience the very best the Mediterranean has to offer. That is why we have hand selected the best dive spots around the Mediterranean.

Diving in a submersible

The unique experience of diving in a submersible has, until now, been enjoyed by very few individuals. We have taken care of the technical requirements involved in diving submersibles. No need to worry about dive permits, weather, or ocean currents. We plan every part of the dive so you can sit back and enjoy the adventure.

Our bespoke Triton 3300/3 3-person submersible, operated by our trained submersible pilot, is capable of diving to depths of up to 1000m below the surface. Thanks to the fantastic design of our Triton Submersible, no compromise has been made for comfort. Fitted with luxurious leather seats, spacious legroom, and panoramic 360° views, diving in our submersible is first class.

Your safety is our priority. That is why we also deploy our second support submersible, a Triton 3300/1 operated by our second trained pilot, to ensure a safe dive.
