The gauge has a first template-like cavity and a first straight edge bordering the first cavity. The first template-like cavity is adapted to enclose an end of an oar blade, and the straight edge is usable for steadying a pitch meter against the oar blade for measuring a pitch angle on the oar blade

The gauge has a first template-like cavity and a first straight edge bordering the first cavity. The first template-like cavity is adapted to enclose an end of an oar blade, and the straight edge is usable for steadying a pitch meter against the oar blade for measuring a pitch angle on the oar blade. In another aspect of the invention the gauge has first and second template-like symmetrical cavities separated from each other by a pendulum member that is movable from side to side to selectively define a template-like trapezoidal shape inside either cavities for selectively gauging a competition-type oar blade on a starboard or on a port side of a racing shell.
