Sea Shocks mats rely on the same cutting-edge Skydex material used in football helmets and running shoes to provide a shock-absorbing deck mat that reduces fatigue and injuries caused by pounding through rough seas. The same material is used on Navy SEAL high-speed assault boats. The 16" by 32" Sea Shocks mats are available in 2 translucent colors and require no installation. They come with a 30-day satisfaction guarantee and a 1-year warranty, and sell for $149. Skydex Technologies, Centennial, CO; (866) 732-7462; www.seashocks.com.
