1. A gauge for rig-related measurements of a rowing boat that has a seat for sliding selectively back and forth on elongate seat-runners which extend longitudinally of the boat, the gauge comprising: (a) an elongate mount having a longitudinal dimension defining a measurement axis of the gauge extending lengthwise of the mount, the mount comprising locating-means to engage the mount with one of the seat-runners to align the mount longitudinally with said one seat-runner, longitudinal alignment of the mount with said one seat-runner aligning the measurement axis of the gauge lengthwise with the seat-runner; (b) an elongate slider mounted on the mount for selective sliding extension lengthwise of the mount in displacement longitudinally of the measurement axis, the slider carrying markings indicative of an amount by which the slider is extended in displacement longitudinally of the measurement axis; and (c) a sighting device carried with the slider for taking sightings laterally from the slider dependent on the amount the slider is extended lengthwise of the mount in displacement longitudinally of the measurement axis.
