The most common material for inflatable boats is high-density polyethylene. This kind of fabric offers stability and protection from punctures. Still, it is lightweight enough to help save on overall boat weight. Some inflatables also use vinyl or PVC—polyvinyl chloride—though these materials are heavier and not as durable. A final option is a hybrid material made with a blend of PVC and fibreglass. These can be pretty strong while still lightweight, but they cost more than other options. When picking your boat, you’ll want to consider its intended use to make sure it has the right combination of toughness and low weight.
