I have one forward cleat line always on the dock and a second that i adjust for wind wave , along with preset stern line that I pick up on coming into slip and toss over cleat, boat glides into dock and then I have second forward line hanging on lifeline midships which i grab as I step off boat and walk to bow to adjust, then toss preset back to bow and attach.
spring lines are then clipped on to toe rail.
Fenders have clips which is preset to life lines.
I use boat weight to coast in idle forward, so the stern line once placed will hold boat in slip iregardless of wind.
Takes a bit to setup but once the lines and setup is right makes for easy in and out.
I singlehand all the time
