Scott , I've been using an Alpaca since they came out. The one person 4.5 pounds if I remember right and can't remember the model name. Has held up well over the years. I bought the spray apron and have never used it. Don't know if that helps. I give some info on using them on my website

If that helps also. Such a good tool for exploring, getting across bays, lakes and down deep canyon s. Fishing also as Liz mentioned! They blow around so easy in the Wind is a downside on lakes that is. And they are expensive. Get the 4 piece paddle if you are going be hiking or backpacking. Mark
