Sounds like a great trip as I sit here buried in the white stuff.
I have one suggestion, it is always safer to do a trip with 3 crew so that there are always two on watch. I know 2 people can do it and I single hand a lot my self but if one goes over when the other is sleeping it is not good.
Unfortunately it happened to a couple of friends of mine. Safety harnesses used properly will of course greatly lessen the risk.
Have a Good One
