I was standing on the dock looking down at a floating dock beside the boat.  Of course, there are lines on the dock with the boards, there are ropes which are referred to as lines for tying the boat, and I have heard people speak of the "lines of the boat"  in figurative terms as one sometimes does in speaking of the architectural features of a car or house.  Anyway, these look look lines to me.
