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.

The invention relates to a rotor sail system (RSS) for a water vessel comprising one or more rotor sails rotatably and multiaxially tiltably coupled with the water vessel which can comprise defined propelling means. The RSS can comprise a drive flange, a defined joint, an end plate, a defined fin, a thermal management system, an array of solar cells and/or two or more superposed portions. The RSS can be configured to provide more sailing regimes, to be at least partially stowable. The RSS can comprise rotor sails of defined forms which can further be coupled with defined electrocomponents and/or mechanocomponents. The RSS can provide data transmissions. The RSS can be provided in a modular system. A rotor sail driving method and a rotor sail assembly method are proposed.

The drag sail has multiple ropes (2) for attaching to a ship (3). A profiled plastic structure in wave form or zigzag is formed by transverse ribs (4). The transverse ribs run together transverse to the wind direction at a distance and exhibit any form e.g. circular, semicircular or square, in shape. The transverse ribs receive the ropes at its end points, and additional ropes (2A) in a middle region. The drag sail is made of plastic or cloth.

A flywheel actuated device for tensioning a backstay cable of a sailboat has a flywheel that is connected to a turnbuckle. The turnbuckle is connected to a cable backstay of a sailboat. Rotation of the flywheel rotates the turnbuckle to increase or relax tension on the cable backstay. The diameter of the flywheel and the weight of the flywheel near an outer circumference of the flywheel allow the flywheel to store rotational energy and cause the flywheel to temporarily freewheel while the sailboat is under sail when a sufficient manual force is applied to the flywheel, which turns the frame of the turnbuckle and provides an initial tension to the cable backstay.

Stabilized rotating sailing rig for boats formed by a mast, a boom perpendicular to the mast, and one or more sails bent to the common boom and to the mast; rig capable of freely rotating with all its elements, around a vertical axis, with the important and novel characteristic that the top of the mast is stabilized by shrouds and/or stays which tie it to the periphery of the deck or decks of the boat without jeopardizing the rotation of the rig around its vertical axis. This top of the mast stabilization also permits the use of prow fixed sails.

A method and a spinnaker launching and/or recovering system releasably attachable to the deck or integrated on the deck or into the hull of the sailboat for launching and/or recovering a spinnaker. The spinnaker setting and/or recovering system has a first spinnaker guide member, which is attachable, e.g., to the bow, a bowsprit or is built into the deck near the bow with an opening through which the tack line and/or a retrieval line attached to the clew corner or to the lower luff of an asymmetric spinnaker or retrieval lines attached to the tack corner and the clew corner or to the lower luff of a symmetric spinnaker. Running with the asymmetric spinnaker, tack corner may be taken forward by a second tack line operated from the cockpit. The first and second spinnaker guide members may be connected by a sleeve, e.g., made of textile, or a solid material.
