Thanks. The tubes are Sotar Legend, 11' (x 21"), single chamber per tube. The frame is a madcatr, 34" between tubes with a 2" drop for the seat. I absolutely love it, it is the perfect boat for doing all sort of silly things in when the water isn't too crazy high. When it gets high (maybe 6-7' on the Lochsa, depending on the section I run), I will break out the 12.5' Legend. The little boat is great because it surfs so easily, but then that is it's downfall as the Lochsa gets burly.
It is extremely light, not only due to the size and madcatr aluminum frame, but since it is single chamber there is less rubber weighting it down.
