This video, shows how quick the wind can change, and why it is accepted thing amongst Kayak Anglers to turn back in if the weather isn't in your favor. I have done it myself when crabbing. sometimes it gets nasty fast. Notice how they are dressed, emergency radio, buddy system, PFD's, flag on the boats. If the swell is long duration you can stay out, but when it gets gusty like that it just sucks!
