How Cruise Ships Maneuver Under Suspension Bridges

With the vast majority of the Earth’s surface covered by oceans, one might assume that cruise ships never encounter any obstacles while sailing. However, the world’s largest all-inclusive cocktail dispensers face a unique challenge when it comes to maneuvering under suspension bridges. These massive ships are specifically designed with features that allow them to navigate under these structures.

The Need for Extreme Measures

Suspension bridges are engineering marvels that span across bodies of water, connecting land masses and facilitating transportation. However, their design often includes a road deck that hangs high above the water, creating a potential obstacle for tall structures passing beneath. Cruise ships, with their towering heights, must take extreme measures to ensure safe passage under these bridges.

Design Features for Bridge Clearance

Cruise ships are meticulously designed to have features that enable them to duck under the road deck of suspension bridges. These features include:

• Retractable Structures: Certain parts of the ship, such as antennas and radar masts, are retractable. This allows them to be lowered or folded down to reduce the ship’s overall height.
• Flexible Funnel Design: The ship’s funnel, which is a prominent feature on its exterior, is designed to be flexible. It can be tilted or lowered to provide additional clearance when passing under low bridges.
• Adjustable Mast Heights: Some cruise ships have adjustable mast heights, which can be lowered to fit under bridges with limited clearance.

Ensuring Safe Passage

Before attempting to sail under a suspension bridge, cruise ship captains carefully assess the bridge’s clearance and consult with navigation experts. They take into account factors such as tides, water levels, and weather conditions to ensure safe passage. Additionally, the ship’s crew closely monitors the ship’s position and clearance during the maneuver.

Despite the challenges, cruise ships successfully navigate under suspension bridges around the world, allowing passengers to enjoy their voyages without any disruptions.
