Rowing-boat gauges
A gauge (1) for rig-related measurements of a rowing boat involves a graduated slider (2) which is slidable longitudinally within a tube (3) that is parallel-mounted via pivoted links (6) on a bar (4). A head (9) of the slider (2) carries a laser (10) and is used with the bar (4) located in a seat-r...

| description | A gauge (1) for rig-related measurements of a rowing boat involves a graduated slider (2) which is slidable longitudinally within a tube (3) that is parallel-mounted via pivoted links (6) on a bar (4). A head (9) of the slider (2) carries a laser (10) and is used with the bar (4) located in a seat-runner 21 to sight its beam B on the swivel-pin (24) or the face-of-work (27) of an oarlock (23). A reading of the slider-graduations is made and then again after the slider (2) has been extended with the head (9) turned down to bring the beam (B) onto the heel (25) of a rowing shoe (26) fixed in the boat. Difference between the readings gives the work-to-heel distance. Measurement of the distance-through-the-work is made from the swivel-pin (24) or face-of-work (27), to either the front end of the runners (21) or the front of the seat (22) when pushed fully forward. In an alternative gauge, the sighting device is a gun-sight mounted on a graduated slider (32) which slides on a mounting plate (37) that has feet (38) for engagement in a seat-runner (21) of the boat. |
