I may try it from the bow and see what happens.
It's nice to follow this thread
Charles is lucky to get your help.
suggest you try with a spring from the forward cleat before you start installing new cleats.
Another option is to use the forward cleat and use a rope strop to keep the line alongside the boat at the middle if you find an attachment point (it's not going to be much load on this stop).
If you take the boat in and have to go forward to get the spring on the dock, you could instruct the owner to use rudder and engine to keep the boat in place while you tie the other lines.
