Wondering if anyone has cut composite oars? Cataract's website says 'do not cut', but I have found a few posts from people who have done it. I found some 10' cataracts at a pretty good deal and was thinking of cutting 6 or so inches off the blade end and drilling a new hole. Wondering if cutting the oars down will change where I need the rope wrap and stop to be? Or if cutting them down will compromise the shaft somehow? Thanks.
