Reinforcing the outer skin of a kayak, the gel coat, with carbon nanotubes makes it more resilient to abrasion from a shingle beach or contact with the edge of a river bank. Baytubes also ensure that cracks appear less frequently over long-term use and reduce wear on the outer skin. In addition, they absorb UV radiation, thereby minimising bleaching and embrittling effects. Re-Turn says the flow resistance of the hull should also be lower. This will enable the kayak to glide through the water faster. The use of Baytubes in the epoxy base also helps to make the kayak more stable and rigid, which makes the boat easier to paddle.
