Although it looks unusual, it’s one of the smartest engineering features on modern ships.
Reduces wave resistance
Improves fuel efficiency by up to 5–15% (depending on the ship and operating conditions)
Lowers emissions
Helps ships maintain speed more efficiently on long voyages
You rarely see it—but it’s working every second the ship is underway.
