Timing !! Try waiting where you can stand, and head off just as the last set is breaking, or shortly after, so you can be part way out when the sets pass, and hopefully finish the paddle out in a lull....
But yeah, timing, then persistence,.... If you're not getting anywhere, there's no harm coming back to shore, and reassessing your options, timing, rips, etc.
Yeah, look for the rips also!
Not aware of any websites.... did you "google" it ?? The back of the Nutri-Grain box was handy for that growing up !!
