Abstract: This invention relates to a cover rolling mechanism for barge covers an inverted U-shaped bar is welded to the push knees of the tugboat and the sheave is supported on top of such bar. A winch is supported nearby on the floor of the tugboat. A cable is entrained over the sheave and pulled by the winch after the end of the cable has been hooked on a double top cover of the barge, which cover, together with other covers protects the lime, or other load in the barge, from rain or other elements of weather. The cable may be re-attached to other covers to affect nesting on top and bottom covers which roll along tracks on the barge. An even central pull is thus affected on the covers.

Abstract: A wind-scoop for small boats has a collapsible framework of resiliant bent wire members, over which a dome-shaped fabric cover member is received in form fitting relation, one side only of which cover member is air permeable for scooping wind to be directed below deck. The bent wire members of the framework, at their lower ends, are provided with radially outwardly-directed hook means for releasable attachment with respect to the peripheral edge of a deck through opening.

Abstract: An outboard propeller drive and steering assembly for a boat. The assembly has an upper housing enclosing an upper drive shaft portion and a steering device support. There is a lower housing depending from the upper housing to support the propeller and rudder. The drive shaft extends through the upper and lower housings and is connected in the lower housing to drive the propeller. A steering device is within and extends from the upper housing and is connected to the lower housing to rotate the same, and the propeller relative to the drive shaft. There is a bicycle-type driving system adapted to be supported in the boat and connected to the drive shaft in the upper housing to rotate the drive shaft. A steering control is adapted to be supported in the boat and connected to the steering device in the upper housing to rotate the device. Bicycle pedals operate the driving system and are positioned to be rotated by an operator in an aft facing position to propel the boat in any direction.

Abstract: A sail line stopper is provided for controlling the hoisting and trimming of sails in which the line may be released under heavy load without abrading the line so released. A U-shaped base member having legs with a pivot pin mounted therein is adapted to be anchored on a sailboat. A cam mechanism includes an inner element having a handle attached thereto which is eccentrically mounted for pivotal movement around the pivot pin. A movable outer element is positioned for pivotal movement and a rotational movement on the eccentrically mounted inner element. One or more springs are mounted between the inner and outer elements of the cam mechanism which are acted on when relative movement takes place between the elements. The spring is compressed when the handle is pivoted placing the outer member in locking engagement with the line in the load direction which locking action is increased with increasing load; while allowing the outer member to rotate or float over the line in the other direction.

Abstract: A gooseneck for rigidly but detachably attaching the boom of a sail-powered vehicle to the mast. The gooseneck includes a mast collar which in the unassembled condition is freely slideable over the mast. A boom yoke receives the forward ends of the boom spars. The yoke is vertically rotatable about a fulcrum provided in the mast collar. Co-operating surfaces in the collar and boom yoke lock the yoke to the collar and circumferentially compress the collar onto the mast as the boom is lowered to a horizontal attitude, thus firmly locking the mast collar, and the boom yoke carried thereby, to the mast.
