Spending years as a Charter fishing business and guide in Prince William Sound, I always thought about what the you look like from below if your in for a dip. Always reminds me of a fish tank when you sprinkle the food on top of the water. Except your the food. Sometimes a client would be reeling up a smaller halibut say twenty pounds or so and all of a sudden bang line would strip, then nothing. Come up the rest of the way with a halibut head. Salmon Sharks, but once, we were bring in some 15 to 30 pound fish, myself or my deckhand would help land, gaff or harpoon what ever was dictated by size. On the port rail a customer was fighting a nicer fish maybe 40 pounds and had the fish to the surface. Well we give instructions to clients to keep the fish in the water. You can lose a fish getting the head out, half the time they go nuts. Well this customer did as instructed and I came to help land his fish. As I'm bending over the rail accessing the fish, bow wake of water with a large grayish shape in it engulfed the halibut and was gone. Bang, 40 pound halibut gone instantly. Scared the crap out of me. A Great White was in the Montague Straights!!! That shark circled my vessel for a while, we had to bring all the lines in and quit fishing. Watching him was quite entertainment enough for me.
