: The float bags are pretty light- probably a pound or less.

Doesn't the material your using weigh about 12 to 14 ounces per square yard ... if so ... how do you end up with a float bag that weighs a pound or less?

The float bags I made out of the Walmart clear vinyl were short to fit the bow of my F1 ... and they came out at about 3 pounds assembled without the inflation tube.
