Details: Tackle your adventures in tandem. The 420x is made to be ridden by one, two or three persons. Now you can do what others only dream of with our most versatile kayak series ever! Designed to tackle whitewater, open-water, and now down-wind sailing! Large enough for two but small enough for one! The420x does it all! Features include: 1) 16 Rapid Self - Bailing Easy To Open & Shut Drain Valves: When the 16 rapid self-bailing drain valves are open, you are sure to drain off water as quickly as it enters! With the drain valves closed you are certain to remain high and dry when paddling on flat waters such as lakes, bays and other bodies of water. 2) Large Removable Rear Center Skeg: A nice feature of this design is that the skeg can be removed with the Explorer inflated or deflated. Simply remove it for whitewater adventures (eliminating it as an obstruction)and replace it for flat water to reduce yawing (swinging to the right or left). This increases track-ability during long flat-water touring, maximizing efficiency and 3) Modular Rigid Drop Stitch Floor Provides Double Protection For Whitewater Action: The unique modular design of the Sea Eagle Explorer features a super rigid, high pressure, drop stitch floor that sits on top of an outside floor. This has several advantages. The high pressure DS floor provides great rigidity and super responsive paddling performance. The reinforced outside fabric floor provides a double layer of added protection so it can bounce off rocks, logs and other objects you may hit in whitewater. The modular design allows the DS floor to be easily removed for quick and thorough cleaning. The Pro Carbon Package includes two Tall Back Seats, bow and stern storage bags for longer trips and two sets of AB50 upgraded top end Carbon-Fiber Paddles.
