I usually post in the Mac section, but I think a lot of folks use the same blue jugs for drinking water on-board so I figured I'd share this to all.
I recently covered my 2 1/2 gallon blue jug with foil backed insulation, which turned out to be a VERY worthwhile project. When we pack the boat I fill the blue jug 3/4 full with ice-cubes from the refrigerator ice maker before filling with tap water. we recently went on a 3 day trip in 95* heat and still had ice cubes after 2 days, and the water was still pretty cold at the end of 3 (kept on the cabin floor most of the time). the test worked so well that I sewed up a cover for it (to match cushions) to protect the foil a bit. The insulation I used was: http://www.speedwaymotors.com/Aluminized-Heat-and-Noise-Insulation-Shield-Double-Sided,32193.html , but I'm sure a similar product is available other places as well. I used foil tape made for the product to tape the pieces of insulation together .
Now we can just take one or two water bottles and re-fill them from the jug, which will save us a TON of room in the ice chest.
