I have one stern line on my boat which goes from the cleat on one side of the A frame to the cleat on the other side of the A frame, across the deck after of the rearmost seat.
When I want to tie up to something I just take it off the side that isn't against the dock/other boat and use that as the free end. No risk of the line escaping - a modest risk of tripping on the rope I suppose but as it tends to sit across where the transom joins the deck, it isn't a problem. If I need a second line, which isn't very often, I have others coiled up in the pod seats.
With hindsight I would have had a couple of small stainless hooks welded onto the A frame that you could take a few turns of rope around and tie it off, but I only thought of that after I got the boat. Happy enough with the way it works though.
A Boat is a hole in the water, surrounded by fibreglass, into which you throw money...
