TUNNEL STERN Meaning and
Definition
-
The term "tunnel stern" refers to a specific type of design in naval architecture, primarily used in boats and ships. A tunnel stern is a construction feature situated at the aft, or rear, end of a marine vessel. It is characterized by the incorporation of an open space or "tunnel" between the hull and the transom of the vessel. This design feature is mainly employed in vessels that require a shallow draft, such as boats that navigate in shallow waters, like rivers or estuaries.
The tunnel stern configuration allows for improved hydrodynamics and maneuverability, particularly in situations where the water depth is limited. By creating a void or recessed area beneath the vessel's stern, the tunnel stern design helps to reduce the amount of water turbulence and resistance encountered, thereby enabling better handling and increased speed. This construction feature also helps to prevent the vessel's propulsion system, such as the propeller, from coming into contact with the seabed or riverbed.
Tunnel sterns are commonly found in various types of vessels, including tugboats, small pleasure craft, and even some larger ships. In addition to their enhanced operational capabilities in shallow waters, tunnel sterns are also known for their stability and improved fuel efficiency. Overall, a tunnel stern is a valuable design element that enables vessels to navigate in limited-depth environments while optimizing performance, control, and safety.

Etymology of TUNNEL STERN
The word "tunnel stern" is composed of two parts: "tunnel" and "stern".
The term "tunnel" refers to a passage, often subterranean, which is typically enclosed or covered. It is derived from the Old French word "tunel" or "tonel", which originally meant a pipe or conduit. This, in turn, can be traced back to the Latin word "tunellus", meaning small cask or barrel.
"Stern" refers to the rear or aft part of a ship. It comes from the Old Norse word "stjorn", which means 'rudder' or 'steering.'
When combined, "tunnel" and "stern" describe a particular design feature in boats or ships where there is a recessed or submerged area towards the rear (stern) of the vessel.
