You are going to get two trains of thought here. While both agree backing plates are needed, how you get there is another!
All of my winches have BIG fender washers under them vs one big plate with smallish washers. The fender washers are to me what is really helping to hold the nuts from getting ripped thru the deck. This is not to say a big piece of metal or plywood would not help! BUT, you winches also are more of a linear pull vs an upward pull on a sheave/pulley of some sort, so IMHO, a backing plate is not needed as bad.
Of course, this is not saying a winch will not pull out or off of a boat.......
I like BIG washers along with backing plates, or big washers alone depending upon the item being secured.
