Abstract: The instant invention describes devices and methods of measuring the differential air pressure at numerous representative points across the surface of the sail or sails and providing visual feedback of areas of ideal laminar flow and areas of less than optimal airflow with a calculation of thrust and providing an indication the maximal differential airflow and thrust. The invention utilizes an array of sensors that detect minute variations in barometric pressure and other data on each side of the sail surface. These sensors are connected together to form a network or net across the sail. This connection can be physical, using wires, or it may be wireless, using for example, but certainly not being limited to, Bluetooth LE 5.0 or other wireless topologies or technologies. This can be extended over multiple sails and monitor not only the sail but the interaction of the sails. Finally it can utilize a combination of wired and wireless connections to fit individual situations and can couple with existing terrestrial and satellite ship networks.

Abstract: The invention relates to a fabric for lightweight nautical sails, such as spinnakers, asymmetric spinnakers, and gennakers, for sailboats and other surface vessels, the fabric being formed of continuous polyester warp and weft yarns and being coated on one or both of its two surfaces with a crosslinked polymer, characterised in that the polyester is poly(ethylene terephthalate) (PET) having a tenacity greater than or equal to 6 cN/dtex; in that the fabric has a density of between 20 and 50 threads/cm, in terms of warp and weft density; in that the polymer is a crosslinked polyurethane (PU) that is polyether-, polyester-, or polycarbonate based; and in that this PU is derived from the crosslinking (1) of a single-component polyurethane elastomer having a modulus at 100% elongation comprised between 1 and 15 MPa, better still between 2 and 15 MPa, in particular between 6 and 15 MPa, according to the standard DIN 53504, used in implementation in solvent phase; and (2) by a crosslinking agent, based on a proportion of dry crosslinking agent relative to the dry elastomer of between 20% and 75% by weight, in particular between approximately 30% and approximately 75% by weight. The coated fabric has an elongation in the bias direction under 20 Lbs, comprised between 10 and 30 hundredths of an inch.

Abstract: The present disclosure is directed generally toward sailing vessels. One example is a catamaran with one or more pivoting masts per hull member, which may pivot from a generally perpendicular upright position, to a generally flat stowed position toward the bow of the hulls. The masts are capable of sustaining a plurality of sails, which may travel 180 degrees with respect to the hulls.

Abstract: 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.

Abstract: Disclosed is a sail comprising a head, a tack, and a luff extending between the head and the tack; a luff region extending along the luff; wherein the luff region has a significantly higher degree of elasticity compared to the average elasticity of a remainder of the sail. Also disclosed is a method of making a sail comprising laying out material to form the sail; arranging material in a luff region of the sail and in the remainder of the sail such that in the direction of the luff, the luff region has a higher degree of elasticity compared to the remainder of the sail; curing or sewing the sail to form a cohesive structure.

Abstract: The instant invention describes devices and methods of measuring the differential air pressure at numerous representative points across the surface of the sail and providing visual feedback of areas of ideal laminar flow and areas of less than optimal airflow with an indication of how the sail must be adjusted to create the maximal differential in airflow. The invention utilizes an array of sensors that detect minute variations in barometric pressure and other data on each side of the sail surface. These sensors are connected together to form a network or net across the sail. This connection can be physical, using wires, or it may be wireless, using for example, but certainly not being limited to, Bluetooth LE 5.0 or other wireless topologies or technologies. Finally it may utilize a combination of wired and wireless connections to fit individual situations and may couple with existing terrestrial and satellite ship networks.

Abstract: Provided is a radar and communications enhanced sail for a sailboat, sail ship, or sail drone. The sail includes a first sail section comprising an active communication system, a second sail section comprising a passive communication system, or a combination thereof. The active communication system includes an antenna array (transceiver) and a software-defined radio (SDR), while the passive communication system comprises a reflective panel or sections and/or array of reflector panels or sections. The active system utilizes its SDR and transceiver to communicate back and forth with an onshore SDR and transceiver to provide information as necessary. The passive system receives a radar signal via the reflective material on the sail and reflects the signal back at the radar, which produces a radar cross section indicating that there is an object (in this case the sailboat) in the ocean.

Abstract: Propulsion apparatus for an aquatic vessel comprises an aerodynamic body which extends along a longitudinal axis between first and second ends and in a transverse direction between a leading edge and trailing edge. The aerodynamic body has one or more external wind-receiving surfaces which extend between the leading edge and the trailing edge, thereby defining an aerodynamic profile of the aerodynamic body in cross-section substantially perpendicular to the longitudinal axis. The propulsion apparatus further comprises at least one air vent and at least one air flow generator configured to expel air through the at least one air vent. The at least one air vent and/or the at least one air flow generator are configured to direct expelled air across at least a portion of the one or more or more external wind-receiving surfaces.
