Abstract: A method of driving a work body to an obtuse angle relative to a drive body by providing a pivotal mounting of a work body such that it can pivot up to 180 degrees, mounting a drive body at a spaced position above the pivotal mount of the work body, pivotally mounting a first end of an elongated lever arm and pivotally mounting the distal second end to the operative end of the linear actuator and providing a drive arm from the work body to a leverage position on the lever arm between the first and second end. Also, the drive arm is pivotally mounted by the drive arm mount to the lower drive body and a sliding pivot slot pin is received in the linear slot extending along a portion of the drive arm to define a direction and limitation of movement of the drive arm relative to the lever arm.

Abstract: A variable geometry anchor for controlling drift of a watercraft including: a support structure; a mast support assembly pivotally mounted to the support structure, the mast support assembly including a pair of mast arms and a foldable or flexible structure attached to the mast arms, the mast arms being movable between a first storage geometry and an operation geometry; an open-close sub-system pivotally connected to the support structure and operatively connected to the mast support assembly at fixed pivot mounts on the mast arms; wherein the open-close subsystem controls the geometry of the mast support assembly such that in a storage orientation the open-close subsystem closes the mast arms substantially together whereby the foldable or flexible structure is received between the mast arms, and in an in use condition the open-close subsystem operatively urges the mast arms apart unfolding and fanning the foldable or flexible structure there between.
