Genre of Surf films/dvds

[guybrush]

hi, i'm wondering the Genre of surf films

Surfari or Adventure: for movies like endless summer, there's i little story, know the word, etc
documentary: like "dogtown and z Boys" things relly happened

how do i call films with surfing waves and nothing more? there is only surf, the usually long 40 minutes. Are this genere "surfing video" or what?
