Abstract

A gauge () for rig-related measurements of a rowing boat involves a graduated slider () which is slidable longitudinally within a tube () that is parallel-mounted via pivoted links () on a bar (). A head () of the slider () carries a laser () and is used with the bar () located in a seat-runnerto sight its beam B on the swivel-pin () or the face-of-work () of an oarlock (). A reading of the slider-graduations is made and then again after the slider () has been extended with the head () turned down to bring the beam (B) onto the heel () of a rowing shoe () 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 () or face-of-work (), to either the front end of the runners () or the front of the seat () when pushed fully forward. In an alternative gauge, the sighting device is a gun-sight mounted on a graduated slider () which slides on a mounting plate () that has feet () for engagement in a seat-runner () of the boat.
