I see there is a new alternative pack raft on the market: ‘The Hornet-Lite is the lightest packraft in Kokopelli’s fleet weighing in at 4.9 pounds (2223 grams) including the seat. Kokopelli has designed the Hornet-lite packraft to be functional while reducing weight and maximizing compactness. This packraft is ideal for crossing rivers, high alpine lake fishing and wide calm rivers’ so says their description: http://www.kokopellipackraft.com/adventure-series/hornet-lite It is a bit cheaper at US$525 than (most of) the Alpackas (http://www.alpackaraft.com/) but may not have the same durability as comparably priced models there. Another cheaper still choice for flatter water is Klymit’s offering: http://www.theultralighthiker.com/klymit-packraft/ Cheaper still is my Faux Pack Raft: http://www.theultralighthiker.com/home-made-pack-raft/
