Personally, I don't have enough experience with hard shell kayaks to compare, however, the Razorlite, to me, feels less stable than the Sea Eagle Explorer or Fast Track models, both of which are very stable inflatable kayaks.
Yes. You can see in the picture that there's a white bar that hooks on each side of the hull right in front of the seat. That's a foot rest.
No it is not. But the quality is very good . It is a great kayac for the money
Thank you for your interest in Sea Eagle Boats. The 393rl comes with a backpack that fits the deflated razorlite and can be checked as luggage, however we advise that you check with your airline regarding each individual airline's luggage restrictions. The deflated measurements of the hull alone is 22" x 22" x 12".
