Owning a small fleet of 13 Seayaks - my favorite is the Azul Sultan which you no longer can buy unfortunately. After owning and paddling the QCC700 my Azul, Sultan out preforms quality and I can paddle just as fast with out trying against the QCC700X. I'm a 60 yr old female 5'5" weighing in at 125 lbs, both boats are considered to big for me - lol, I've had no problem with boats being too big for me. You can be bigger built and not have the strength to paddle either.
Noticed Riot Kayak makes a boat very simular to the Sultan, if I'm not mistaken Azul had some interface with Riot prior to going out of buisness, maybe the new Riot, Sea Kayak is the same boat - still checking that one out. If anyone has the facts on this please inform me as I really love the Azul, Sultan. If they went out of buisness I feel it had to because they made to much of a good boat for the money, they lost out. Only my opinion as to the quality and handling of the boat I own and paddle, my FAVORITE over all. The Azul Sultan :-)
