I recently purchased a used Chester Yawl that came with 8' oars. I found it very difficult to row. After the stroke it was difficult to get the oars back to start since I had to straighten my legs out to return them to the start position. The standard oar is suppose to be 7' 6". It just doesn't seem like 6" difference would be enough. I am 6' tall and everything else about the boat seems standard. Since I live in Alaska getting oars sent up that won't work is a concern. Will the 6" do the job or is there something else going on that I am missing?
