That's not being an a**hole, that's a legitimate question. Currently I have a base pack weight of around 12lbs for a week long trip (having issues getting under 10). Thats without a float tube. With all my float tube gear it about doubles it, then I have to add another 5lbs or so for a bigger backpack. A lightweight float tube would make a huge difference. It would basically allow me to carry it into the back country. Right now I only take it to a few lakes and most of the time I just go lightweight and fish from shore. It's just too big and bulky to take everywhere. As far as the weight question, I'm 6'0 and 148lbs. I'm trying to get up to 155-160 and maintain that, but it's not easy for me. Losing weight to shave off 5lbs wouldn't be a good idea. If/When I build a sub 3lb float tube, I'm sure it would only have a weight capacity of 175 or so. Depending on how the project goes and how successful the product is on the water, maybe I could make a few larger ones that were sub 4lbs (still under half the weight of most float tubes). That could offset some cost if I decide to get a real heat sealer.
