Too much fun. That's how I should always start a Stand Up Paddle Surf post.
I remember when it happened. Back side smack of the top, I can still feel the board get loose. Not that I'm some kind of power surfer but I tend to break fins, always the same one, always on back side snap off the top. Almost every board I have I've had to had the fin system, fin box, fin re-glassed. Right hand trailing fin. Mikey I'll be calling you!
Paddle with Aloha!!!
