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. The bearings allow the portaging thwart to rotate about its axis relative to the canoe. The axial rotation of the portaging thwart in turn allows the canoe to rotate backwards and forwards relative to the canoeist, thus enabling the portaging thwart to maintain a constant position relative to the shoulders and neck of the canoeist as he or she ascends or descends sloping terrain. Stops are provided in the bearing assemblies to limit the range of rotation so that the canoe does not pivot too far during ascent, decent and while lifting the canoe, and locks are provided to prevent unwanted rotation of the yoke during storage or transport of the canoe.
