I do not think that you are being a pain in your question, I just think that they cannot do a video of every scenario.
First, I think that your buddy line is a good thing...I would hate to see a pretty blue hull scratched. Buddy could be a good name for it if you want to keep your slip neighbor as a friend
OK, an attempt to answer your question with a scenario somewhat similar..I think.
I sail a Catalina 34 (very similar), my slip faces S and I have a fairway the same width that I enter from E to W. I have a port tie which works well with our prop walk (I think that prop walk is a friend) but this works with a starboard tie as well. When the wind is NE and above 15 (quite often) it wants to push me forward and also away from the dock. YOu have to come in somewhat hot...but under control.
First thing I do every season while in my slip is mark one of my longer dock lines (any line can be used) as a spring. I attach it at mid ships, run it back to the cleat or post I want it over on the end of the dock, and run it to the cleat on the stern. I then adjust it so that when the boat stops it is close enough that I can attach both bow lines (which I leave on the dock when not traveling) without having to throw lines or stretch. I adjust the spring so the bow is a foot to 18" from the dock in front when stopped. I then mark that spring line so I can pre-attach it at both ends prior to entering the marina. If I am traveling I also pre rig bow lines only for entering strange marinas.
Where I may do things somewhat differently is in the approach but every boat handles somewhat differently. However, I have put Catalina 30's, Catalina 32's, and 36's in my slip with this type of wind...so not that different on a Catalina hull form.
I enter the fairway slowly and shift into and out of gear to keep boat speed low. I don't use reverse as it affects steering too much. I will obviously use it if I have to stop. I get the boat speed to around 2-2.5 knots for control purposes. I turn 90 degrees into the slip which accomplishes a few things. One, it slows the boat some more as I enter the slip. Two, the momentum does not allow the wind to push the 12,000 pound boat around (Force counteracts force). I then use throttle or lack of to slow the boat dependent on the day. When the boat is partially in the slip (about 1/3rd) I shift to reverse in idle or more if the wind is strong. In my case this can help pull me to port and the dock. If I am in a transient slip it is reverse idle so it slows me and does not pull me away from the dock too quickly.
After I make the turn into the slip I then pick up that spring line and prepare to drop it over the end post of my dock (cleats work equally as well or you can rig something). I am at the wheel (same place as yours) with one hand and the spring in the other. I drop it over the post and then apply enough pressure on the line to begin slowing me more by hand. I then put the boat back in idle forward and pay out the line until the boat stops at my pre marked spot and is still in forward. Adjust the wheel so that the power pulls you to a point where you want the boat to sit while you attach other lines. Keep the boat in idle forward while you attach those lines and then fine adjust.
In my case at home I leave both bow and stern line on the dock so the boat always sits where I want it in the slip. I let the spring pull me to the dock, adjust the wheel so she is straight in the slip, leave her in gear at idle, step off the stopped boat, go forward and attach the bow lines, walk back to the helm and take her out of gear and use the same spring line to pull the boat back in her slip and attach the stern line. If it is really blowing, after attaching the bow line I put her in reverse and let the engine help me pull her back for the stern line attachment.
In your scenario the two things that struck me as being a problem for me would be the reverse throttle in the fairway and turn and a slow turn. Every situation is different and they might be best in your case. I would be concerned about lack of control while in reverse and losing too much speed because of it. A certain amount of speed is a good thing, too much is an accident waiting to happen, too little subjects you to the vagaries of the wind. The other is the slow turn into the slip. In my case I like to use that keel to spin her and take the wind out of the equation as much as possible. Nursing her in makes me slow and I can be blown off in light winds let alone high winds.
Notice that I do not have a line with loops at both ends. That will work, and well, for some people, but I have never found the need.I like the control of a longer line. I can then use the post or cleat to slow the boat and don't have to wait to get to the end of the line and go BOOM! This is also a very controlled situation when done correctly. The boat does not slam to the end of the spring and jam against the dock. However, that has also happened.
Try it and see if it works. If not, do what I did and find someone who does it well and have them help you. In my case I hired an instructor for a day of specific single handling practice. Docking, sail trim, tacking, gybing, etc. as a single handler. Interestingly, he had worked with Jack Klang who at one time worked at the sailing school. Also, I picked the instructor for his strenghts, I did not take the luck of the draw. If you don't want to hire an instructor, walk the dock with a beer and watch people dock similar boats. You will definitely know immediately who you DO, and DO NOT, want to learn from. Congratulate them on their fine boat handling skills and ask if they might be able to help you sometime. A small compliment works wonders!
