Abstract: A multi-purpose bracket which clamps across both gunwales of a canoe and presents a standardized pad at each side of the hull to align precisely and mount rigidly a variety of accessories. These accessories include multi-hull catamaran coupling bars, portaging wheels, and any other equipment requiring a temporary but strong and secure means of attachment. The very large forces and moment loadings generated by such accessory equipment are borne directly by the bracket's strong tubular beam and then transmitted safely to the hull by distributing them through both gunwales as simple direct tension and compression forces. The standardized mounting pads provide a common basis for future development of many accessory devices that can enhance both the utility and enjoyment of canoes, while enabling such equipment to be shared and used interchangeably by any canoe equipped with a bracket according to the invention.

Abstract: During the portaging of a canoe by a single canoeist, discomfort may be caused to the shoulders and neck of the canoeist. The discomfort is due both to the pressure exerted by the portaging thwart on the shoulders and neck of the canoeist and to the rotation of the canoe and hence the portaging thwart relative to the shoulders and neck during the ascent or descent of inclines. Much of the discomfort is alleviated by the present invention which provides a portaging thwart capable of axial rotation relative to a canoe. In this way, relative to the canoeist, the portaging thwart remains stationary while the canoe rotates, thereby permitting the canoeist to place the portaging thwart at the optimal angle to his or her shoulders and neck, independently of the angle of the canoe. In one embodiment of the invention, the portaging thwart is mounted in bearings attached to the gunwales of the canoe at approximately the mid point thereof.

Abstract: A hanger for suspending a boat fender alongside the hull of a boat to prevent damage from collision with another boat, a dock or other object near which the protected boat is to be tied or berthed. The boat fender hanger is hung from a suspension cable on the protected boat, such as a guard rail or lifeline, and a suspension line attached to the fender is secured to the hanger. The hanger can be transported easily from one position to another on the cable and it has an anti-detachment feature which reduces the risk of accidentally losing the hanger and fender overboard. The hanger provides the ability to move the hanger from place to place on the suspension cable and to adjust the vertical elevation of the fender using only one hand. The novel hanger has an elongated body separated from a back plate by a channel which receives the suspension cable for hanging the hanger.

Abstract: An apparatus for laterally bracing and/or suspending outboard rigging from the sides of floating vessels and the like. The outrigging apparatus comprises a spar with a padded end at its base and an outer end that includes a bore for reeving the outboard rigging, especially roll-dampening devices. The spar sets mainly below the rail of the vessel and is supported by a harness which provides the spar stability on the hull-side of the vessel, where it extends perpendicular to the hull-side, and at some inclination from the base. When a load is applied to the outboard end of the spar it is balanced statically between tensions in the harness and compression along the spar. The basal pad mitigates the resultant pressure on the hull where it contacts the topside. Only two existing attachment sites are required onboard the vessel, one to each side of the extended spar. Whereas the spar is not permanently attached to the vessels' side, it is quickly and universally deployable.
