Here's a vessel that tops the SS Bessemer in weirdness. This little oddity is the
SS Ernest Bazin, an experimental ship built in 1896 to test inventor Ernest Bazin's roller ship concept. The vessel floats on and is partially propelled by six disc shaped hulls/wheels, each of which are independently driven by a 50 horsepower engine, with an additional source of propulsion through a small screw lowered from the main deck.
The idea behind this design was to create a faster vessel by reducing hull contact with the water and by increasing the number of propulsion sources, this being achieved by having multiple independent hulls that also act like paddle wheels when rotated. Bazin himself predicted that the test vessel would be capable of 18 knots, however in theory it could achieve speeds up to 32 knots.
However when she was tested in the English Channel, water adhered to the rollers, causing a braking effect, thus preventing the ship from reaching its predicted top speed and causing it to consume more fuel. While the test roller ship proved to be a failure, Bazin continued to work on the design and in 1898, several weeks before his death on January 21st, Bazin announced that he had found a solution to the fault on the rollers and that he planned to build a transatlantic liner with four pairs of rollers capable of 47 knots, but the roller ship concept ultimately died with him.
