yeh no doubt
I also had this image from The Old Man and The Sea come to mind.
So you land this fish and then you try to bring it into land a monster marlin being dragged behind your surfboard leaking its lifeforce into the water in a variety of fluids, since death brings about the release of all kinds of fluids and solids. A very terrifying thought in my books. It is one thing to catch fish from a boat but from a surf board you are like steve irwin baby. I mean that in a kind a strange good way not in the way that I hope ya get eaten.
Now one other thing that comes to mind since man knows more about the surface of the moon than they do about the ocean. What if you actually hook something like a giant squid or some other monster in the ocean what then, who has actually caught who. What if the thing you hook on the line is way more powerful than you suppose off you go with wind surfing of another type.
