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 variable trimaran that uses natural power has an outer hull, which is capable of ensuring stability with respect to a center hull in the middle thereof. The variable trimaran can be selectively expanded and contracted in the horizontal and vertical directions thereof. The variable trimaran includes a sail unit, which uses wind power, and a solar power generation unit so as to enable efficient long-term sailing without the use of fossil fuel. To this end, a horizontal and vertical adjustment units are provided for adjusting the position of the outer hull, and the solar power generation unit and the wind power sailing unit are used such that the position of the outer hull can be freely adjusted with respect to the center hull and efficient long-term sailing is enabled without the supply of an oil energy source due to the use of sunlight and wind power as power sources.

The present invention discloses a system for measuring pressure on a sail comprising: a) at least one pressure electronic scanner; b) at least one pressure sensor positioned on the sail; c) pneumatic means for connecting said at least one pressure scanner to said at least one pressure sensor positioned on the sail, wherein said connecting means is a pressure strip.

One embodiment of a deployable structural system having sandwich-like shell stiffness and strength properties is constructed of an outer elastic sheet and an inner elastic sheet connected by a number of substantially rigid webs wherein hinges constitute the connections. The hinge connection spacing dimensions on the inner and outer elastic sheets differ such that the resulting assemblage may be elastically bent into a compact cylindrical configuration. Deployment is achieved through reversal of the bending process and application of sufficient external restraints such that the deployed configuration is structurally stable. Additional application embodiments are described.

The sail force gauge utilizes an electronic system to measure the vectored force of the mainsheet or jib sheet. By gaining the vectored force of the sheet, a relative vectored force upon the sail can be acquired thru simple trigonometric equations. To obtain the vectored force measurement, a multi-axis load cell will measure the force in the lateral and axial directions. These forces can be used to calculate the vectored force of the mainsheet. By knowing the dimensions of the boom length, the sheet block positions, and the vector angle, the resultant angle of the boom can be calculated as well as the perpendicular sail force acting upon the boom. From these calculations, the relative axial force acting upon the boat can be calculated.
