Advantages of SubCat design
Sail in the same conditions as a conventional surface vessel
Having a process from surface to submerged and vice versa is very exciting for the passage
The diesel-powered, surface-sailing autonomy allows it to access the optimum dive sites
The center of gravity and the center of hull of the 3 models optimize stability in all sailing conditions
Maintenance is less costly than on conventional submarines , as it is carried out like a surface vessel
The main access hatch to the passenger cabin is located aft of the cabin , which makes it very easy to pass from the cockpit or the passenger surface navigation area to the immersion cabin
The main propulsion batteries are located in the hulls of the catamaran, which substantially improves cabin air conditions and eliminates the risk of toxic gaseous elements
The subcat is designed to dive to a depth of 30 meters, with a maximum safety depth of 45 meters
The dive depths where the most marine flora and fauna exist are at these depths , as well as the luminosity
Beyond about 30 meters the visibility becomes exponentially worse , and yet the cost of design and construction for these depths is much higher
NavalSub has developed the technology to enhance SubCat designs and optimize the operative, increasing the capacity up to 40 passengers (including 2 crew members).
Conventional submarine for private purposses
This project is aimed to develop a conventional submarine, with storage capacity and cabins for crew and passengers, for longer travels but for private purposes.
- Passengers + crew: 6
- Speed: 8 knots
- Autonomy: 3000 NM
- Maximum depth: 50 m
Naval design
NavalSub develops the design of each of the models, adapted to the customer's needs.
Detailed engineering, R&D
Once the design has been adapted, NavalSub offers the possibility of developing alternative products, their technical feasibility and the detail study that defines the concept best suited to the client's needs.
Construction up to turnkey delivery. Assistance and maintenance
NavalSub carries out all the design, technical development and construction through the Galician shipyard NODOSA.
Once built, NavalSub offers the assistance service to train the client's crew, according to the safety regulations and IMO rules; build/assemble the necessary shore structure for the correct maintenance of the vessel, and permanent assistance and operational maintenance service.
