You have some good advice there from the fellow sailors.
Assume you will have wind and tide. The midship dock post has a fender on it. It should be secured top and bottom so it does not shift. Check the tidal range for size. Also put one fender on the stern dock post. Note your companion on your starboard has no fenders. You should put out 2 ball fenders to starboard.
You will note that there is a line between the boats running from the portside outside pole to the dock. When you come in you can grab that line and pull yourself in. Or you could pull yourself half out.
However, you have a problem going out. As you proceed in reverse and you start making your stern move to starboard, your bow will go to port, possibly hitting the dock or aft dock pile.
It will be a major problem in a crosswind against the dock. When you go out the wind will tend to pin you against the dock. This would not be a problem if your slip were 3 slips to starboard. You would just go straight out and have room to maneuver.
You might want to consider backing the boat in. When backing, stand up at the stern facing the stern. Less confusing. This way you grab the pole line almost before you are in the slip. And don’t wait to turn stern first when near the dock. Do it out in the channel.
Leaving the dock bow first will be a snap. You can also bring the boat out of the slip and launch from the dock without having to turn the boat around.
Your slip is challenging, but you’ll be a better sailor next season.
