That's all true unfortunately. A 13 ft boat needs bigger oars, no
question about it.

You've gotten some good advice on oar locks also. My personal
preference would be round ones with collars on the oars. On a safety
note, "U" shaped oar locks must be removed at all times when not in
use. They are a serious source of injury if someone falls on them.
