The super-durable WaterMat Shark is made from industrial-strength foam specifically engineered for commercial marine applications. Designed to withstand the rigors of the heaviest daily use, the WaterMat Shark is 50% tougher than the Original WaterMat EX...so tough that it comes with a three-year limited warranty (in residential use). So tough that the Shark is the WaterMat of choice for the 24-hour Ultimate Tough Mudder test of endurance. At 22-feet in length, the WaterMat Shark offers unrivaled durability and quality. The WaterMat Shark is ideal for camps, resorts, and other commercial placements, as well as for the largest, toughest families! The Shark uses our Double Grommet System for stability and security. And even bolder is the WaterMat Shark Plus...26.5-feet of jaw-dropping, teeth-clenching fun! REVIEWS Thrilled!! - 07/08/2015 Reviewer: Jamie PriceThe Shark is wicked... boaters are already stopping and asking where it came from. The whole experience was super easy, delivery was a breeze and we had it on the water and anchored in a matter of minutes. and It's going to be a great summer!!! 06/10/2015 Reviewer: Carol TerryberryTough and durable! The anchor system is well thought out so it won't pull through in heavier chop/waves. Havnt used yet but Im EXPECTING it to survive many yrs of summer camp.
