I'd put thruster[s] on our Tolly if I needed to. Luckily the designers [Monk and Tollifson] spread our props fairly wide off the center. And... they put on good sized rudders close to each prop.
Result is a twin screw cruiser that reacts very well to its engines' props and the rudders. When docking in most cases... I make sure the rudders are straight ahead and maneauver the boat exclusively with trany shifting and mellow bursts of power [forward or reverse per engine] as needed. For quick turn on just about its length... one engine in forward and one in reverse with power applied as required
I do my close quarter maneuvers at VERY slow speed. Idle rpm works wonders when using shifting sequences and gentle power bursts.
Another good handling chariatic of our Tolly: At idle rpm on both screws with engines synchronized, by using the helm or shifting the engines [bumping rpm if desired], she's no problem for maintaining a straight line cruise or creating a turn.

Haven't found any particular difficulty docking with single engine and bow thruster. Find strategically-placed fenders to be helpful, coming and going.
Also, the thruster counters any unwanted prop-walk while in reverse.

Would love to have a bow thruster. But I have twins and the cost doesn't pencil out for me. I can swing in or out and with the proper rudder position I can walk side ways.

Yes, why have three motors when two will do.

an electric bow thruster means nothing unless you have a good size battery bank, in good condition. Use the thruster(s) sparingly.

Have needed only a few short thrusts from the thruster. No indication of power shortage from the house batteries. Perhaps having a 24-volt system.

Never be afraid to start over.
Learn which direction the stern of your boat wants to back when the rudder is centered. (prop walk) Watch the bow too.
Practice 'back and fill'. There are many videos on YouTube.
Never be afraid to start over.
Above all, dont let those around you or on the dock, see you sweat. CHUCKLE

Yes! Never be afraid to abort attempt and start over. More than a few occasions I've pulled back out into the fairway and turned around. Easier to do that than try and correct a botched landing.
Also, I'd say learn to you use pilings to pivot off of. I've used mine plenty of time to catch the bow or stern and then use thrust to pivot around it. BUT! Learn where your boat likes to pivot! To far forward on the bow, my boat likes to pivot OUT and away from the piling. The complete opposite of what I'm trying to do.

One common theme in this thread Is fenders. And from my experience applied here, lots of fenders. Given the length and beam, probably not a lot of room for fender storage. Have you considered inflatable fenders as part of your arsenal? Assuming you aren’t headed out for a lot of short trips where deflating and inflating would be a hassle, you could store a few larger round fenders for use undocking (and maybe docking) that could be deflated and stowed. A 12v pump would make the process relatively simple as you get ready to return to your slip. Then you can use spring lines and the dock wall as much as you want. Just trying to think a bit out of the box is all - remove the root cause of the anxiety (crashing into the dock) so you can focus on executing what you’ve visualized...

and some 8D batteries.
I had the wimpy bow thruster replaced on my N46. They put in a switch to automatically give it 24vts. Double props..... Was one of the best improvements I made on the boat. just a bit of touch touch touch and the bow would swing.
The AT34, 12vt. 3X4D. I still have to watch the voltage.

In your situation and depending on how hard the wind is blowing. I would walk my boat back until the bow would clear the boat along side of me. I would use a forward stern cleat spring line and a large stern fender. Back into the spring line until your bow is turned into the wind and go forward and release the spring line.

Why not do that but walk the boat to the end of the dock?

That's an interesting technique... questions:
Often the swim platform hits the dock first, so we need some sort of fender for that, and are there any made (that work)?
If you can get the stern slightly past the end of the dock, great, but often one is on a side tie of a bunch of boats and only a few feet on either end of the boat. In which case, seems like backing out is easier.
But.... looking for suggestions on getting the bow away froma dock, especially with a strong wind fighting it.

When I was a new owner and inexperienced, I crunched my swim platform. I had it removed and never in six years of ownership and extensive cruising including a Great Loop have I ever missed it, wished I had one, or ever perceived a use for one. We have transom davits for our dinghy. A swim platform would just get in the way. Just one one opinion among thousands.

Many are on hinges. Hinge up before docking. They are very convenient when living at anchor as loading/unloading a dinghy with food/liquids is very difficult without one. Especially in a chop. They’re also helpful when Med moored.

I guess some folks feel different. I wouldn't even consider a boat without a swim platform... use it all the time. Launching the dinghy, kayak, swimming, great platform for exploring the bottom of the boat, etc. And, yes, they do get in the way for maneuvering from a dock.
