Cigar ship
A cigar ship was a ship with a cigar- shaped hull from the mid-19th century. The brothers Ross and Thomas Winans built at least four of these ships between 1858 and 1866 as technical experiments which, although they attracted a great deal of media attention, never actually undertook ocean voyages. Even later, this type of ship did not catch on.
According to the plans, the cigar ships should be less sensitive to swell than normal ships. Due to the shape of the hull of the cigar ship, however, there was no righting torque , since the center of gravity of the tubular hull, regardless of the position in which the shafts turn it, remained in the center of the tube. The ship therefore tumbled in the waves and was unusable. The drive with a single large propeller also turned out to be unsuitable.
