Painted? Of course they are painted, all of them and also decklines are mandatory. They aren't a sea kayak if they don't have decklines and bulkheads. That's 6 plus three kids kayaks. Admittedly the folding one (#7) isn't painted. On the other hand my partner's kayak is varnished. Not sure what she's going to do with the one she's building at present. What ever, it will have decklines.
Also they all have rudders, the later ones fitted with the daggerboard style of rudder, the one that KajakSport a decade later got round to redesigning badly and Sealect a decade after that. Both claim they have patents on something that has been in commercial production long before they started.
