The Manta is designed to be a highly competitive kayak for extreme races. At 272cm it is within the allowed length limit and the most noticeable features are the aggressive bow rocker and stern spoiler . The purpose of the rocker on the bow is to lift and clear holes whilst keeping you on track & in control to move forward. The stern "spoiler" design assists in exiting holes by boosting the boat forward & out to maintain your momentum; great for speed in a race and equally useful for surviving gnarly hydraulincs.
