Shark skin coating

I was more worried about it soaking up water like a wetsuit.

I've tried hot air balloon material before, it lasted a whole five minutes.

Right now the thermal polyurethane I'm using, heat welds great with a household iron, but will not hold heavy duty upholstery polyester sewing threads well.

 

George,

You need tough. Start with these type of materials. http://www.apexbelting.co.uk/

That's what I once thought, but the heavy stuff over water gets sucked down and causes drag. Plus it's not responsive which means it's dragging on the ground as well.

The Russians use some heavy stuff for operating on ice (mostly) and that's what works for them.

What I'm using now is a coated on one side and only lighter version of what large Commercial/Military hovercraft use today.

So far it's wearing great but no one-part glue such as contact cement will work with it. It's apparently heat-weld only friendly.
