My air boat,less than 360g!

Warning. Photo downloads to computer. Uncool.

Use second link. If you read Chinese. Need more photos of the boat.

the following pictures show the status of boat body and inflated airbags(<250g),not including waterproof layer(<110g):

Hi~Ken,I have changed the old links,you can visit my website to see more large pictures.

The carbon fiber paddle(black) is 420g.

Very nice Ke Wu.

The weight is impressive, and the design looks very tidy. Can you post more photos, Ke Wu? I'd love to have a better understanding of the bladders, valves, and envelope. What materials are all of these components made from?

I'm not asking these detailed questions because I intend to build a boat, by the way. Just impressed and curious.

Hello Colin~
The bottom structure of the boat is divided into four layers, from bottom to top as: ripstop nylon, dyneema layer, ripstop nylon and waterproof membrane fabric. The waterproof layer can be separated from boat body, both of them connect each other by velcro. I choose 18" latex balloons as airbags. Generally speaking, the single layer balloon is quite safe（one-off use）, but double layer balloon is more safe. However, don't let the balloon contact with the wet sand, somtimes it will cause troubles.

Ah. Balloons. When you say there is a Dyneema layer, do you mean Cuben?

This layer is a kind of things(left), very similar to cuben(right),but much stronger,I think.

Sweet! Nice job if it works well and is durable.
