The Carlisle Oar Right keeps your oar blade in the right position for full-power strokes.
Note: Instructions that come with the Oar Rights say to put a screw (which is provided) through the tip of the spline into the oar shaft. This is only applicable if you're using it on a wooden oar. DO NOT do this on Carlisle or Cataract oars, it will damage the shafts.
Large: Adjusts from 2" to 2 1/4" (Carlisle & Cataraft Oars with Oar Sleeve)
Small: Adjusts from 1 3/8" to 15/8" (Bluewater Oars and Economy Oars using XS Oar Sleeve)
