One of the fastest swimming fish in the ocean, Sailfish occupy the very top of the oceanic food chain. They can swim up to 68 mph, so imagine what it will be like to try and land one of these on fly tackle. Not only do they swim like rockets their powerful jumping can provide you with one of the most exciting experiences you can have in deepwater fishing. They can be found throughout the Atlantic and Pacific Oceans. Their large size and spirited fight make them a favorite among trophy fishers. These powerful, streamlined beasts can grow to more than 10 feet and weigh up to 220 pounds. When hooked, they will fight vigorously, leaping and diving repeatedly, and sometimes taking hours to land. They are predominantly blue to gray in color and have a characteristic dorsal fin known as a sail, which often stretches the entire length of the back. Another notable characteristic is the elongated bill, resembling that of the swordfish and other marlins. They are described as billfish in sport-fishing circles.
