The Ultimate Sub Support Expedition Vessel

Vessel Description  *Note- video had length wrong - it is 101 ft or 30.8 meters

The 30.8 m Motor Vessel ALK (ex: Alkor) was built in 1965 in Germany as a research ship for renowned German research institute GEOMAR. ALK logged an impressive 326,000 Nm roaming the Baltic Sea and North Sea, until she was replaced by a larger research vessel.

In the 1990s ALK was refurbished in the Netherlands to become a private pleasure yacht. In the 2000s ALK received further upgrades to operate as a submarine support vessel, all while maintaining he excellent seagoing characteristics and character.

Her top speed is 11 knots and she boasts a maximum cruising range of 4,000 Nm at 9.5 knots. Power come from a 425HP Deutz diesel engine, which operates very economically at 60 liters/hours at cruise speed.

She can accommodate up to 13 persons and is the ideal vessel for an owner looking to cruise the world with a highly seaworthy and spacious vessel that is a mix between a capable workboat and a yacht.

Equipped with an 8-ton certified A-frame crane and integrated dive center, ALK can handle a wide range of submersibles - yet adding another dimension of exploration.

ALK was dry-docked in the first half of 2023 for extensive works on the keel, hull and propulsion system. The vessel has been fully maintained and is ready to sail.

Motor Vessel ALK will be delivered with a U-Boat Worx C-Explorer 3 - 300 meter rated submarine
