In the winter time, I use a 20gal rope handled tub 2/3 or 3/4 full of water, outside, filled 24hrs or so ahead of time depending on how cold it's going to be (less if it's going to be real cold). When my boil is over, I kick a hole in the ice and drop the pot right in. It will float just fine with the lid on and I periodically stir the water and the wort (with different paddles).
I have two tubs and will be using both of them tomorrow night for my next brew day (eg. when the wort reaches 140 or 130 transfer to the next tub). Maybe I'll take temp readings with time stamps to see how fast I can get the wort below 100º.
