Various embodiments of a submerged submersible sailing vessel are disclosed. Such a submerged sailing vessel may comprise a submersible hull assembly, a keel coupled to and extending upwards from hull assembly towards a water surface, and a wind-catching assembly coupled to and extending upwards into the air from the keel for propelling the submerged sailing vessel. The hull assembly and the keel are submerged below the water surface as the vessel is propelled by the wind-catching assembly above the water surface.

A system for autonomous ocean data collection includes at least one sensor capable of collecting sensor data, at least one transmission device, and at least one computing device comprising one or more hardware processors and memory coupled to the one or more hardware processors, the memory storing one or more instructions which, when executed by the one or more hardware processors, cause the at least one computing device to generate data for transmission based on the sensor data collected by the at least one sensor, and cause the at least one transmission device to transmit the data.

A sailing boat includes at least one mast with at least one first and one second section projecting upwards with respect to the hull and arranged facing each other in the orthogonal direction to the advancement direction for supporting a mainsail in two mutually specular and alternative operating positions, where the sections are connected and spaced out from each other by at least one overturning section of the mainsail placed at the top of them to allow the passage from one specular position to the other. The three sections of mast define for that purpose a first sliding guide for the whole mainsail that extends substantially along the whole extension length of the mast and the mast includes a second sliding guide positioned substantially at the top thereof and placed aft with respect to the overturning section.

A rig for a nautical craft includes a reference plane intended to coincide with a symmetry plane extending in longitudinal and vertical direction of the hull of the nautical craft; —at least one wing; —at least one rigid support capable of supporting the wing and transmitting a propulsive thrust to the hull of the nautical craft given by the aerodynamic lift generated by the wing when it takes wind. The wing includes a first and a second main face opposite to each other, the rigid support being capable of supporting the wing at least in a first operating configuration in which at least a main portion of the first or second face is facing a first side of the reference plane and in a second operating configuration in which the main portion is facing the opposite side of the reference plane; the rigid support includes a wing sliding path for switching from the first to the second operating position and vice versa.

Techniques are provided for an unmanned surface vehicle including a vehicle body and a rigid square-rig wing coupled with the primary vehicle body. The rigid square-rig wing includes a first surface configured to interact with wind to generate a force that propels the primary vehicle body in a direction of travel that is primarily composed of drag, and a second surface configured to interact with the wind to generate a force that propels the primary vehicle body in a direction of travel that is primarily composed of lift. The unmanned surface vehicle further includes a rudder and a control system comprising a controller, the control system configured to determine a rudder position and generate a signal to position the rudder to the rudder position.
