A double-ender is a type of boat that is propelled by two engines and has two pointed, symmetrical bows. This type of boat is extremely efficient, as both engines are utilized in powering the boat forward and can be steered from both ends. This design allows for quick changes in direction and is often used in activities such as fishing and water sports, due to its manoeuvrability. This type of boat is also used in commercial applications, as it is able to navigate tight spaces with greater ease than other boat designs.
