The Big Game Mat by Ortho Mat is a must for any boat owner. We all have been there...feet up, legs sore after a long day in rough water offshore. This painful feeling is brought on by the constant compression of our joints as the boat "bangs" its way over and through the chop. The orthopedic endorsed Marlin Mat absorbs over half of the impact acting as a shock between you and the boat. Constructed of multi-purpose PVC Nitrile closed-cell rubber. Mats available in sizes below, with custom sizes available, please call for additional information. Also great for kneeling on the deck or down in the engine room.
