Retractable rope/leash?

I apologize if this has been asked but my iPad doesn’t like the search tool here.

Is there a retractable rope or other leash I can use when launching off a trailer? I thought about a heavy duty retractable dog leash but wonder about it breaking (bye-bye boatie). I just don’t like having a rope inside the boat.



Painter Line Under Bungie
A lot of canoers use a short painter line (rope) that is held at the bow/stern under a short bungie cord. That way is stays stowed when not in use. Seems that would do what you want without the entanglement risks.
