I have the same issues as Rhythm, 3 marinas down river from him.
The end tees have have fast current with slack water measured in minutes, and a slightly more gentle current closer to land.
I am inside the tee on a narrow fairway with a 6hp outboard.
Returning to the slip against the current is a pleasure, throttle back to just enough speed for slow progress and nudge the finger pier as I come in, step off and secure the spring line, then pull and adjust the bow and stern lines.
Returning single handed with the current is another mater, outboard in reverse or not the boat is charging into the slip at 3kn +. I aim to strike the finger pier with the fender forward of the shrouds, standing holding the shrouds as I come in, step off secure the spring line then grab the bow or stern line before the offending boat end strikes my neighbor.
Gusting winds make the process even more interesting, and I am exposed to 3 miles of open water down river.
