The finished Brandtaucher, built by August Howaldt of the later Howaldtswerke was 28 feet long, weighing about 70, 000 pounds.

As at that time no suitable mechanical power system was available the submarine was powered by two sailors turning a big tread wheel with their hands and feet.

The third crew member, the captain, was positioned at the stern of the submarine.

His job was to operate the rudders and other controls.

Having arrived under the target ship the captain would reach out through a gutta percha ( rubber ) glove fixed to an opening of the hull, grab the mine located within reach on the hull of the submarine and fix it on the target.
