Use a plug in style GFCI to the buffer. I used a special shore power cord that was modified with a 3 prong outlet at the boat end, plugged the GFCI into it, and when the buffer got accidentally dragged into the water, it clicked off. Same as when the buffer cord drops into the water and you turn on power---it just clicks off. I used this method for ten years buffing boats in the water.
Just make sure every step you take is deliberate and keep a handhold in reach if you're walking around the cabin or anywhere narrow or slippery.
Always wait until morning dampness moisture is dried before starting.
For the hull, below the rub rail:
Since boat sides don't oxidize like topsides, a cleaner wax is all you should need.
Start with a washdown with a boat soap or hull cleaner. When it's dry, (assuming you have access to both hull sides, and the bow area, even if you have to turn it around after doing one side), get a simple kitchen mop called a Quickie, with a sponge surface. The type that has a handle on the shaft that you can squeeze water out works best.
Using just a bit of water to moisten the sponge (you don't want it wet, just moist), spread some Meguiar's Fiberglass Cleaner Wax on it and rub vigorously on the hull sides, doing 3-4 passes up and down, next pass is one sponge width next to the first.
Repeat.
You can do the entire hull down to the waterline without breaking a sweat.
Don't touch the bottom paint with it!
The little red scrubber pad on the other end of the sponge works well on stubborn black marks, etc.
When it's dry, the hardest part is removing the wax, but since it's a cleaner wax it should be pretty easy.
Whatever you do, do not use the same brand of cleaner wax that is made for cars or you'll be fighting to remove the wax until August.
That I'm sure of.
I used a gadget I found at HD made for cleaning windows to remove wax in bow areas that were out of reach. It had a T shaped plastic shaft at the end (on an extender pole)and came with a sleeve that slipped over it that looked like a fluffy wash mitt. It removes a decent amount of wax before you need the remove it and shake it clean. You can also blue tape a small towel over it or make something similar with an automotive car window cleaner/squeegee like gas stations have (or used to!).
