  • Patent number: 9422043
    Abstract: A vessel provided with at least one rigid wingsail installation with a mast structure and a rigid wingsail. The mast structure comprises a foot and a mast top which is rotatable about a substantially vertical wingsail rotation axis relative to the vessel. The mast top is provided with a primary tilting assembly. The rigid wingsail comprises a main panel connected to the mast structure via the primary tilting assembly. This assembly allows tilting of the main panel relative to the mast top about a primary tilt axis. The rigid wingsail also comprises a top panel which is connected at its lower end to the upper end of the main panel via a secondary tilting assembly. This assembly allows tilting of the top panel relative to the main panel about a secondary tilting axis.

  • Patent number: 5673641
    Abstract: A wind-propelled hydrofoil comprising a forward assembly with at least partially submerged forward foils and a fully submerged aft foil. The forward foils (43, 44) are such that the resultant of the vertical forces drops when said assembly is translated vertically upwards, with a heave characteristic (F), and increases when said forward assembly is subject to upward pitching, with an incidence characteristic (A). The aft foil (46) has an incidence characteristic (R) such that R(d-g)-Ag+F(g.sup.2 +r.sup.2)>0, wherein d is the distance between the aft foil (46) and the center of heave, g is the distance between the center of gravity and the center of heave, and r is the gyration radius of the hydrofoil.
