A method of programming and setting parameters for a computer unit that regulates the interface between the operator of a marine vessel and the vessel's electric generation and propulsion systems. The invention describes the regulation of energy producing devices, energy storage devices and drive motors and propellers in both propulsion and regeneration modes. This invention simplifies and automates most of the operation of marine electric, hybrid electric, or diesel electric propulsion because the only controls requiring operator intervention are three generator modes: OFF, AUTO and ON, an alarm, an override switch and one or more throttle(s). This helm control can be duplicated in different areas of the vessel. All automatic modes required to regulate forward movement, reverse, emergency power, zero drag, propeller freeze and regeneration are all controlled by a logic using a combination of generator mode, the position of the throttles, the speed and the stored parameters of the vessel.

An assembly for controlling a vehicle, including a fluid contact surface constructed and arranged to act against a fluid passing over the fluid contact surface; and a support structure coupled to the fluid contact surface. The support structure is constructed and arranged to expand or contract between a first position and a second position, such that a first dimension of the support structure changes during movement of the support structure between the first position and the second position, while a second dimension of the support structure remains substantially constant during the movement of the support structure between the first position and the second position.

A method for verifying a control system (2) of a vessel (4), in which said control system (2) in its operative state receives sensor signals (7) from sensors (8) and command signals (9) from command input devices (10), and as a response provides control signals (13) to actuators (3) in order to maintain a desired position, velocity, course or other state of said vessel (4), characterized by the following steps:

• • during a time (t0), disconnecting the reception of real sensor signals (7a, 7b, 7c, . . . ) and replacing said real sensor signals by a test sequence (T0) of artificial measurements (7a′, 7b′, 7c′, . . . ) from a test signal source (41);
  • letting said control system (2) work based on the artificial sensor signals (7, 7′) to generate control signals (13′) to be recorded as a response (S0) to said first test sequence (T0) for said first time (t0) on a control signal logger (42) and storing response (S0) to the test sequence (T0) as the control system's (2) “signature” response (S0);

said method having the purpose of, at a later time (t1, t2, t3, . . . ), to use the test sequence (T0) input to the control system (2), and record a later response (S1, S2, S3, . . . ) and determining whether said later response similar to the signature response (S0) to verify that said control system (2) is unchanged, or not.

A control device for a steering kite on a boat. The steering kite can be steered by a steering device and at least two or three, preferably at least four or five, suspension lines. The control device comprises at least one force introduction rail that extends horizontally over the water line and on which a deviation device for the suspension lines is positioned in such a way that it can move back and forth. The rail is fixed to the boat between the steering kite and the steering device in such a way that the traction force of the steering kite produces torque about the longitudinal axis and/or the transverse axis of the boat in the water, by means of which the leeward side of the boat is lifted upwards.

The invention relates to a fin stabilization system adapted to minimize roll about the longitudinal axis of the boat during sharp cornering at very high speeds. In one form, equipment such as a machine gun is mounted to the bow of the boat and targets are adapted to be engaged in high-speed maneuvers when cornering and the deck of the boat is not excessively rolled whereby blocking visibility in a turn.

Apparatus, systems and methods for connecting two seismic streamers are disclosed that enable two streamers to be towed in a desired arrangement. One apparatus comprises an elongate member having a first portion and a second portion, and an orientation member connected to the elongate member between the first and second portions, the orientation member functioning, when the streamers are connected by the apparatus and towed, to maintain orientation of the streamers. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

A system for adjusting a deflector in a seismic survey comprises a generally upright deflector body and at least one bridle connected to a seismic cable. The bridle includes an upper segment secured to an upper connection point on the deflector body, and a lower segment coupled to a lower connection point on the deflector body. The upper bridle segment, lower bridle segment and deflector body define a geometry between themselves. This geometry is adjustable by at least one actuator so as to control the tilt angle of the deflector body

A watercraft includes a number of subassemblies, including an inflatable hull, a drive system, a battery, a seat assembly and a steering and thrust control. Each of the subassemblies of may be of one or more particular designs which are detailed herein. A watercraft in accordance with the teaching herein may use one or more of these designs and each such watercraft is within the scope of this disclosure.

A paravane for a marine seismic survey system includes a float and at least one diverter operatively coupled to the float. The diverter is configured to redirect flow of water past the paravane with respect to a direction of motion of the paravane through water. The paravane also includes a steering device. The steering device is configured to controllably redirect the flow of water so as to control an amount of lateral force generated by the paravane.

Portable power generating devices are provided for converting potential energy from flowing water, water current, blowing air or air current to mechanical and/or electrical energy. The potential energy is converted to a rotational movement, and the rotational energy is communicated to power conversion units for conversion, wherein the rotational movement is converted to mechanical, electrical or some other useable or useful energy.

A network system using a LAN to provide relative position data for a engine in a plurality of outboard motors attached to a watercraft and using that data to display engine condition information for each engine in the array of engines installed on the watercraft.
