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.
