Stern

The rear or aft-most part of a vessel.

The stern is a critical part of any boat or ship, as it is the section located at the very back of the vessel, opposite the bow (the front). Historically, the stern was often ornately decorated, especially on older sailing ships, but in modern vessels, it is designed more for functionality and hydrodynamics. The stern is where you will often find key components such as the rudder, which is used to steer the vessel, and in many cases, the propeller(s) and engine(s) are also located here, particularly in motorboats and ships. 

In terms of design, the shape of the stern can vary depending on the type of vessel and its intended use. For example, a flat or transom stern is common on many modern motorboats, providing a stable platform for mounting engines or for passengers to board and disembark. On the other hand, a cruiser stern, often found on canal boats, provides more deck space for socialising or working. The shape and design of the stern can also affect the vessel’s performance in the water, including its speed, stability, and how it handles waves. 

Additionally, the stern is often the location of important safety features, such as lifebuoys, and it may also serve as an access point for dinghies or tenders. Understanding the function and layout of the stern is essential for safe and efficient vessel operation.
