Gas-proof envelopes are show-stoppers for cheap skyboat construction. Exotic hydrogen-proof fabric is expensive to make and is time-consuming to cut sew perfect gas-tight seams. These fancy but temporary envelopes become holey and leaky very quickly. They're fine for millionaires' balloons but impossible for the working slobs' envelopes.

We can not use gas tight envelopes. We will use plastic bags inside the envelope for holding the lift gas. We will use plastic film to form the aerodynamic skin that contains the polyethylene cheap Lift Bags.

Faster, simpler, easier and cheaper. That's the only way to put the workin man in the sky.

All this cluster balloon pilot needs is an aerodynamic envelope, some propulsion and he's made himself a very affordable SKYBOAT!
