No my answer again displeased you because it went out of your relm of absolutes. Any person that has been on a river or lake long knows you can row or paddle one handed and from one side. I would actually prefer it to oar locks as you can in that manner rest each arm and paddle from the other side a while. Maybe not as fast but you get there just the same. BTW go either to the bow or stern of the boat as it makes it even easier. But you can steer even ore locks this way skill and experience is the key. Watch a team of rowers sometime or a person in a canoe. You won't steer in circles long till you learn to correct. :>}
Now you're getting the point! :D Thats what I am hoping you will do with those heretical and aberrant doctrines. Stop going in dead-end circles .... learn to correct them so you can go straight! :D
