Re: Docking single handed...
For The situation you described, I like Jeff's method. If the pole is 15' high, and a PIA to reach, you could rig the tether with a Caribiner or a snap shackle at one end and instead of messing around trying to get a loop over the pole just wrap it and snap it back on to the shackle. Once you've backed in and secured a stern line. You can go forward and attach your bow line however you want.
