Carbon/Foam Core Hull Support is the foundation that allows the shortest, lightest, newest freestyle kayak design by JK to break all records for weight, performance, and fun. This is our easiest boat to get vertical ever, also loops huge, surfs faster, and takes off a wave easier/bigger than anything we have ever done! Never has a plastic boat been so light and so stiff! Unsurpassed performance is the name of the game here!
