Why is urethane film used for the hull?
FirstLight Kayaks is the first to introduce the use of an unsupported urethane film for the lower part of the hull. The term unsupported indicates that the material is solid urethane and is not a matrix that has been urethane coated. Urethane is highly UV stable, elastic and abrasion resistant. Because of its elasticity it conforms to the 3-dimensional underwater section of the hull without the need for separate panels with longitudinal seams. This is an advantage because it reduces the weight of the canopy. Furthermore the urethane is energy absorbing. If the kayak is placed on a rock, the canopy will deform through the elastic urethane without placing excessive loads on seams or zippers. Because the urethane is unsupported, it can be provided clear or coloured and the clear option offers the user visual access to the underwater world. The clear hull will eventually yellow slightly with age but this has no effect on strength or abrasion resistance. For those seeking a stronger hull, w
