Sounds like lots of oars being pinned due to hydrolics,...helpful hint and a must in my opinion;

Most oar locks come manufactured to tight especially for comp oars. Oars "should" pop out of the oar lock when need be, hence the reason for carrying a spare oar. Oar lock problem is easily fixed by taking two 1" pipes and prying the oar locks open (while yer boat sits on the trailer) just enough to where you can pop the oar out with some force by hand.

Can be a big time life saver in a bad situation!!
