Janssonius Review

AdventureSmith Explorations’ Janssonius review includes a detailed description of the small ship including deck plans and a photo gallery.

Choose the Janssonius for a state-of-the-art new ship whose name says it all: In 1612, when the ship’s namesake, Jan Janssonius, married Elisabeth de Hondt, daughter of another famous cartographer, Jodocus Hondius, they created the first ties between the Janssonius and Hondius families. Together with his brother-in-law, Henricus Hondius, Janssonius published atlases in a time when traveling by ship was opening entire new worlds to European explorers. Most notably the Janssonius-Hondius team enlarged the Hondius Atlas, later renamed Atlas Novus.

Janssonius boasts strength, high-tech stabilizers and the utmost in safety standards. Like her sister ship Hondius, Janssonius is primarily defined by an exploratory educational travel program, with guests spending as much time ashore as possible, including special interactive workshops, captivating exhibitions and vibrant performances on board and on land.

With the most modern equipment available and decades of sailing experience behind the design, Janssonius is being built according to the latest requirements of the International Maritime Organization (IMO), in particular concerning the safety of the life at sea (SOLAS) and the prevention of pollution from ships (MARPOL) for passenger vessels. Her construction took place in Croatia, by famed shipbuilder Brodosplit. She is be powered by two main engines delivering 4,200 kW, just like her sister ship Hondius. Her stern and bow thrusters enable Janssonius to drift or remain comfortably stationary.

Also like Hondius, the propulsion system of Janssonius includes an adjustable pitch propeller, flexible power management, and a shaft generator as opposed to a diesel-driven generator. This keeps Janssonius at the lowest fuel consumption and carbon dioxide emission possible.
