Sailfish vs Marlin

As a fellow fishing enthusiast, I can understand the curiosity surrounding the differences between marlin and sailfish.

With their striking appearances and impressive speeds, these fish have captured the hearts of many sport fishermen worldwide. But what sets them apart?

In this article, we’ll dive into the key differences between marlin and sailfish while answering some of the most popular questions.

Physical Differences: Marlin Vs. Sailfish

Marlin and sailfish are both members of the billfish family, known for their elongated, spear-like bills. However, there are noticeable physical differences between the two:


  • Body shape: Marlins have a more robust and cylindrical body with a thicker bill.
  • Size: Marlin are generally larger, with some species, like the blue marlin, reaching up to 16 feet in length and weighing up to 1,800 pounds.
  • Fin: Marlin have a shorter dorsal fin that runs along their back, usually not reaching their tail.


  • Body shape: Sailfish have a slender, more streamlined body, with a thinner bill.
  • Size: Sailfish are smaller in comparison, with an average maximum length of 10 feet and a weight of 90-200 pounds.
  • Fin: Sailfish are known for their large, sail-like dorsal fin, which extends almost the entire length of their body.
Feature Sailfish Marlin
Body Shape Slender and streamlined with a thinner bill Robust and cylindrical with a thicker bill
Size Average length of 10 feet, weighing 90-200 pounds Some species, like the blue marlin, can reach up to 16 feet and weigh up to 1,800 pounds
Dorsal Fin Large, sail-like fin extending almost the entire length of the body Shorter dorsal fin that runs along the back, usually not reaching the tail
Speed Up to 68 miles per hour Up to 50 miles per hour

Speed: Which is Faster, Sailfish or Marlin?

One of the most commonly asked questions is, “Which is faster, sailfish or marlin?” Sailfish are considered the fastest fish in the ocean, reaching speeds of up to 68 miles per hour. Marlins, while still incredibly fast, clock in at a slightly slower pace, with top speeds of around 50 miles per hour.

Eating Marlin and Sailfish: Are They Edible?

Many people wonder if marlin and sailfish are edible, and the answer is yes, but with some caveats. While marlin is more commonly consumed and can be found in restaurants and markets, sailfish is less popular due to its tougher texture and strong flavor.

Additionally, eating large predatory fish like marlin and sailfish can come with health concerns, as they may contain higher levels of mercury. Pregnant women, nursing mothers, and young children should be particularly cautious.

Catching Marlin vs. Sailfish: Which is Easier?

As an angler, you might be interested in knowing which fish is easier to catch.

The answer is definitely subjective and depends on various factors like location, technique, and experience. Sailfish are almost always considered easier to catch (also easier to catch in greater numbers) due to their abundance in certain fishing grounds and their tendency to feed closer to the surface.

However, some anglers find the challenge of catching a marlin more exciting due to their larger size and strength, which makes for one heck of a fight!

Fun Fact: One location where Marlin are as easy to catch in greater numbers is the Dominican Republic, specifically Marina Cap Cana just south of Punta Cana.

In Conclusion

So, is a sailfish and a marlin the same?

While they share some similarities as members of the billfish family, there are key differences in their appearance, size, and speed. Both marlin and sailfish offer unique and thrilling experiences for anglers, and understanding their differences can deepen your appreciation for these incredible creatures.

Whether you’re a seasoned fisherman or a curious ocean enthusiast, I hope this article has provided you with valuable insights and inspired further exploration of these fascinating fish.
