More than 80% of the ocean is unmapped, unobserved and unexplored. Very few people will have the privilege of exploring the depths beneath the waves in their lifetime, but U Boat Navigator can make this dream a reality.

U Boat Navigator is a one-of-a-kind explorer and dive support vessel available for charter through West Nautical. U Boat Navigator is completely unique on the market today and is the perfect solution to a standalone explorer charter or as a charter support vessel to another superyacht.

Involved in the initial discovery of hundreds of wrecks and well over 500 submarine expeditions, U Boat Navigator is a celebrated yacht and team in the underwater exploration industry, taking part in world famous dives and documentaries and consulting on submarine affairs worldwide, including the superyacht industry. U Boat Navigator offers charter guests a once-in-a-lifetime opportunity to dive to depths of up to 1,000 meters and explore historic wrecks from the safety and comfort of a proven Triton submersible, and at the same time have their experience immortalised in a professional video.

U Boat Navigator is also the perfect charter vessel for guests who love scuba diving. The vessel is equipped with the very latest personal diving equipment including nitrox and trimix mixing panel and a custom-made wet diving bell with automatous hydraulic crane and surface supplied gases, operating to a depth of 100 meters. This enables divers to dive to wrecks that are usually out of reach, and enjoy their time on the seabed more and return at appropriate speed comfortably to the surface from the safety of the bell. Diving equipment also includes four professional sea scooters. On the lower deck there is a custom-made four-person decompression chamber, a gas filling station with the capability of filling all types of breathing mixtures for the appropriate depths for both submarine and scuba dives, thus allowing for months of autonomous diving, and a medical station.

Inside, guests can enjoy the large bridge salon with interactive chart/dive plotting table where during dives they can watch the live video links from the remotely operated vehicle (ROV) which streams directly to the media room. On the exterior, the vessel has the benefit of a large superyacht-style covered flybridge complete with lounging area, bar and alfresco dining options. The flybridge also benefits from having a large projector screen on which guests are able to enjoy movies and clips of the day’s diving filmed by the professional media team onboard. U Boat Navigator can also accommodate six guests in three ensuite cabins.

The media team onboard will shoot and edit a professionally made 2-minute, 4k quality video of the charter for all 7+ day charters, with longer videos and different edits being available under further negotiation. Safety is always the priority amongst the 6-man crew, with the onboard doctor being fully certified to use the advanced medical equipment, including the decompression chamber.

Based in Malta, the vessel has access to all wrecks and dives sites in Maltese, Italian and Greek waters.
