The Subcat Catalonia stands as the world’s sole operating hybrid tourist submarine, having undergone an extensive refit that included the installation of new viewports, diesel engines, a significant portion of the electrical wiring, batteries, modern automation systems, high-pressure storage, and a complete internal sandblasting of the ballast tanks, which form the hull. By the end of 2021, it achieved compliance with the classifications set by the American Bureau of Shipping (ABS), Australian Maritime Safety, and the International Flag of Vanuatu.

Given its hybrid design, the Subcat Catalonia falls under the regulations of SOLAS concerning the safety of operations. It adheres to ISM Codes, holding a valid Safety Management Certificate (SMC) issued by the classification society on behalf of the flag state. Additionally, the company has secured a Document of Compliance (DOC) Certificate and is listed on the IMO Shipping Register.

However, the submarine’s innovative features and classification restrictions have led to exemptions from obtaining a Passenger Ship Safety Certificate, MARPOL Certificate, MLC Certificate, and International Ship Security Certificate. Despite these exemptions, it possesses all necessary documentation for international operation within its restrictions, pending local authority permits for diving sites.

The Subcat Catalonia’s hybrid design allows for flexible relocation, offering a comprehensive partnership package potentially under a Submarine Management Agreement. This arrangement would leverage the submarine’s capability, crew, and expertise, while the partner would manage local permits, customer relations, and shore-side services.

A key advantage of this submarine is its dual propulsion system (diesel/electric), enabling it to independently reach dive sites. Passengers benefit from easy access through a horizontal hatch and experience genuine submerging and resurfacing, facilitated by the Pressure Hull’s above-water position. This design simplifies viewport maintenance and extends the vessel’s lifespan. Unlike other vessels, it features a passenger deck for surface travel.

Originally certified for 28 passengers and 2 crew members, it now accommodates an additional staff member (Passenger Guide), bringing its capacity to 27 passengers. This adjustment is subject to regulations by Registration/Maritime Safety Authorities rather than the classification society.

The submarine is capable of carrying 27 passengers and 3 crew members, reaching depths of up to 30 meters. It operates underwater using electric power and employs two diesel engines for surface navigation.
