Jaws - Harpoon

Hanging from the headstay, Mike drew his arm back and took aim. "For you, Sean," he grunted, and flung the iron with all the strength he had.
The harpoon sank into the shimmering, shining flank, buried itself up to the transmitter, and quivered.
The shark did not even flinch. Off-balance from the throw, Mike tottered on the bowsprit, managed to cling to the headstay, and pirouetted around it.
He was helpless, suspended on the water. He drew back his free arm, felt a sandpaper snout brush his hand, and heard a snap like a giant steel trap.
He caught one last glimpse of the eye and saw a cold, cold promise that someday they'd beet again.
The shark crashed back into the water in a sheet of stinging foam. The shaft of the harpoon broke off, leaving its point and the transmitter well embedded in his flesh.
