I have the Sea Eagle 420x and absolutely Love It. My wife and I have taken on a few trips this year and it has overwhelmingly exceeded expectations! I expected that I would give sacrifice something regarding durabtility, maneuverability or stability, but that is far from the case. We are not experts by any means, but have used canoes and kayaks of many forms, and this has excelled in all cases. Great Job! I also have to add that when I had questions, or had to follow up on adding on to the unit, or getting additional paperwork, Customer Service was polite, and Fast. One of the best I have ever dealt with, Period!
