The largest of the versatile Explorer Series, this rugged and durable inflatable kayak weighs only 42 lbs, can handle up to Class IV rapids and is also great on the open-water. If you plan on camping, overnight trips or just plain need the extra storage space. The 420x is the kayak for you! When the 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. 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.
