Simple, let her operate the boat and YOU handle the lines. That's what I do and have a remote thruster control in my hand. She has never had a problem doing that, but most of us men are much bigger that our partners and can handle lines much easier.

Has anyone tried this?

Many times. I currently back out of my slip and have to back up about 300 feet before I can turn around. Slowly works pretty good, occasionally coasting. And both thrusters help with keeping it straight, but don't need them much. Just as easy to use forward to straighten out.

Well, I actually donít have a lot better balance than she does. She doesnít like to run the boat, she knows how but she would only do it in an emergency. We have the thrusters so it works well for us.

Good point, but if her safety is in jeopardy, I'd argue to dock single handed and let her do nothing, not worth her safety. I'll often do that when my co captain wants to sleep.

She handles the stern line when we dock. We have a huge swim platform since we put the extension on it. Makes it easier for her to board, the dog too. Our bow lines are always on the bow cleats and run back to the stern spring cleat. She does the stern line and steps onto the dock, undos the bow line from the spring cleat and makes it fast to the dock. Some variation of that is our normal procedure. No one has to climb up onto the bow to handle lines. It wouldnít work without the thrusters to hold the boat to the dock while she carefully does her line work.

Great threadÖ just learned that I can convert my side power thrusters to proportional. Might consider that as very helpful holding the boat in high winds/currents. Guessing a few boat bucks.

Yes, it isnít cheap but you can run them for a much longer time if needed.

The short answer is NO.
Practice, learn docking with spring lines and 'back and fill'.
Will a stern thruster make life easier for you? That is your decision.

A caution; unless you have hydraulic thrusters, you must have the batteries to support the demands of the thrusters

On my single, the bow thruster reduces transmission abuse. The "barn door" rudder serves as a stern thruster.

Transmission abuse is debatable. Most hydraulic marine transmissions will survive an incredible amount of shifting in and out of gear provided the engine is at idle.

,,,,and the cabling to carry that large of a current.

This discussion gave me a great idea. I am going to get rid of the starter motor and heavy cables and battery in my cars and install hand cranks! That will be less maintenance and increase my mpg. I can probably cancel my gym membership as well. Thanks for the inspiration!

Years ago, there were spring started engines. Hand cranks to put tension on the spring then release tension spinning the engine and hopeful the engine, if it didn't start, "do over".

There was also hydraulic starters with nitrogen accumulators. You would pump up the pressure in the accumulator and let fly into the hydraulic starter motor. Same drill, no start, start pumping again. There were also straight air starters which were favored by gasoline haulers, but you need an air compressor and a fairly large reservoir for that.

I have hired an experienced big boat captain and his mate to help speed the docking learning curve on our new to us motor yacht. We jumped from a 46 GB to a 65’ Pacific Mariner. Adding in the swim platform gives us an LOA of 70 feet. She has a hydraulic bow thruster that is really powerful. The captain won’t let me use it until I am proficient at docking without it. He says you never know if and when the thruster will fail. Plus, if you are proficient without it, you will see it as a value added tool rather than a necessity.

Looking back at your original post...

And your TF join date (2012)... I'd have thought you'd know by now if you need a stern thruster or not.

As a person whoís had both single and twin engines without thrusters, I definitely have an opinion.

Would be nice, but Iíve never viewed them as essential. I might think differently if I had one, but never grew up with that.
