Good for the girls. I am an older surfer and switching to longer board. The kids bother me as well and take off in front of me on their short boards. I yell at them where it really jammed me up or was dangerous. The pay no atention and just glare and do it again. So I try to avoid them. I can get waves before them on my longer board, but do not want to run them over or do anything to endanger them. Things were way different than the old days on the South shore were younger surfers had respect for the older guys. I would definitely step in if I saw the kids harassing somone else whether girl or boy.
