We are going down the Yukon again and are knee deep in the planning stages. The last time we were there it was 70 degrees for several days early in the hunt. That would have been a disaster if we had meat hanging. Our options would have been to take a day or two and try to have it flown out. That seemed like a crap shoot that it would be taken care of properly though not to mention expensive and logistically challenging while remote. The other would be to call the trip and get out while the meat was good, sacrificing a week of the trip and the opportunity for more moose. As it turns out, the moose we shot was when it cooled down, so hanging it at night or building a mound of sticks on the ground worked just fine. We have two jet boats, inboards, and will be hunting fairly close to the river.
We have discussed how to let the river keep the meat cool. The yukon is about 50 deg. F. One option is to leave it on the bottom of the boat and let the aluminum conduct heat away since the hull is being cooled by the river. That is a problem though because it is hard to keep everything dry.
We are kicking around the idea of bringing a bunch of tubing and a small electric pump. We can wrap the meat with the tubing and pump water around them to cool them. We would use one of the 4 boat batteries that will be on the trip and rotate them out to charge when the boats are running.
Any thoughts or ideas?
