I am looking at options for high alpine lakes. If anyone would be willing to let me borrow a lightweight float tube or Alpacka it would help me greatly as I never used either, and am torn. There is a MOTHER pack in it for you.
Why not get one of the lightweight rafts? If the Curtis ones are still available, they weighed 27 ounces, complete with pack bag and paddles. The Sevelour (spelling) weighed in ad 3 3/4 lbs and wasn't as durable but was cheaper.
Both are lots lighter then waders, flippers and a float tube. Those should total in the 12 lb range.
