Dousing yourself with a hose will put you at a disadvantage in any scenario Canoedogs - if you don't have available dry clothing you may be relegating yourself to either starting a fire for warmth (iffy and may be alot of work around here in the PNW, depending on season), or a long night of walking and wakefulness, using up your energy to keep warm. I know one hiker who fell into Thompson Lake one day and spent the next 24 hours awake and keeping warm. He was lucky, he knew the trail home and started out by moonlight around 2am, but before that he had spent about 6 hours walking in a circle to stay warm. By the time he hit the trailhead he had pretty much dried out except for his socks and boots, and he had blisters. Ultralighter, once - the guy never left for a hike without a change of clothes again.
