I converted all my winches to electric, as I single hand my 49. It was a safety issue, if anything.
I do not like the E Wincher, and other similar devices. I know that it saves money over the built in motors, but I’d need a minimum of 2, as I wouldn’t be switching it from port to stbd.
The install isn’t trivial, as the wire guage is 2/0..
I suggest going with the ELS controller, especially on the larger winches
One thing about electric winches…..
If you’re going to use them for hoisting dinghy, man aloft, etc.,, do not use the self tailing. There are some pretty bad stories about this, which you can read about online
If you are going to use a remote control with the winch, make sure you are very ready to shut off the main disconnect. The small cheap remotes are not industrial grade. Make sure you use a flayback rectifier if you are controlling an inductive load
