  • Patent number: 4546718
    Abstract: A sailing ship (1) has at least one mast (2,3,4) rigidly attached thereto, to which the yards (5 to 9) are rotatably attached. By an actuating shaft (21), the sail (22, 22a, 22b) can be reefed and, with the aid of a corresponding rope (24), it can be erected or stretched. The sail (22, 22a, 22b) is narrower in the middle than at the edges and has upper and lower boltropes (48, 49) that are guided in grooves (27) to the yards (5-9). Erecting and reefing of the sail (22, 22a, 22b) and bracing can be accomplished by remote control. Because of the high speed that can be attained, energy recovery is possible with a propeller.
