For maximum strength and good looks, all YAM inflatables are constructed using the latest generation HEYTEX® PVC material, with all seams and joints glue-bonded for optimum watertightness and safety. The result is a smart, clean exterior surface that is highly resistant to abrasion, salt water and sunlight.

Built to take the pressure

A cleverly designed air baffle system is incorporated into the hull tubes of all YAM inflatables. This not only helps to keep the individual chambers completely sealed for safety, it also helps maintain and equalise air pressure throughout the tube. Amongst other things, this also allows your boat to absorb minor impacts without major problems.

In addition to safety features like strong, secure grab-handles, seat patches, D-rings, lifting eyes and other fittings, comfort is also a top priority. Our ingenious high-quality air valve is a good example – exceptionally reliable and airtight, it’s easy to operate and is flush with the surface of the tube, preventing snagging or discomfort.

Easy to transport
