My friend has a problem with pulling his oar(s) off the pins when he is really rowing hard. He tried opening the clips so the oars could be slid back on the pins quickly, but it still takes two hands. He wanted to switch to oar locks & oar rights since they are easiers to get back "into-the-game" with one hand.
However I think his real problem is that his pins are to far forward, and I suspect that at the end of his stroke he is pulling the oars toward himself, and pulling them off the pins.
Has anybody else had trouble dislodging pin/clips or oar lock/oar rights ?
