Do any of you have any creative ideas on how to overcome the limited number of cleats at the stern?
Do you have a Slot ( for lack of a better term ) at the base of your cleat, that you can pass a line or two through...then create a loop (s) with a bowline that would sit on above your primary loops.....that you can attach additional lines to...?
caribiners might be useful ?
Run a jackline fore and aft that could give you some intermediate tie off points with a non-slipping knot?
With no secondary cleat..it all comes down to that one strong point holding.
