The world's second motorized submarine "Resurgam" (Renaissance) was built by Cochran & Co in Berkenhead, designed by the priest from Manchester William Garem. The boat was launched in December 1873. It had a length of 15 meters, a diameter of 3.3 meters, a weight of 30 tons and was operated by a crew of 3 people. The spindle-shaped hull with sharp bow and stern withstood a pressure of 5 kg per square meter. cm, which allowed the boat to dive to a depth of 45 meters. The central sections of the hull had a wooden trim. The boat was equipped with a closed-type steam engine, patented by Eugene Lamm in 1872 and used in the locomotives of the London Underground trains. He provided 4-hour uninterrupted work. The armament was to consist of a pole mine.

After successful trials, during the transition from Berkenhead to the port of Portsmouth to demonstrate to the Royal Navy a technical malfunction forced the crew to moor in the port of Riel for repairs. After the repair was completed, at night in stormy weather, the boat was towed by a yacht on a steam engine.

During towing in the engine of the yacht there were problems and the crew of the submarine went to the yacht to fix them. The hatch of the submarine did not close from the outside and was left open. The boat began to draw water, the towing cable burst under additional load and the boat sank on February 25, 1880 in the area of ​​Riel.

The submarine was reopened at the end of 1995, when it was hooked on by networks of local fishermen. Resurgam is entered in the register of protected underwater objects.
