I've see that Russian guy thing before, pretty amazing what determination can do with little resources.

The issue facing many of the weight sensitive home built hovercraft builders is the foam will absorb moisture right out of the air/atmosphere.

You don't even need a pin hole leak, leave it out in the rain, or floating in the water for the weight gain due to air moisture content to show up.

Maybe a car can deal with this weight gain better than a hovercraft.

I do like that the foam is an energy absorber in case of accident though.
