sternpaddle

sternpaddle refers to a type of propeller system used on some boats where the propeller is located at the stern or rear of the vessel. This arrangement is distinct from traditional outboard motors where the engine and propeller are mounted on the transom, or inboard engines which are located within the hull and drive a propeller shaft that extends through the hull.

Sternpaddle systems can vary in their design. Some might involve a submerged motor unit directly attached to the stern, while others could utilize a more complex arrangement with a drive shaft. The term is not as commonly used as "outboard" or "inboard" and may sometimes be used to describe specific, less mainstream configurations. The primary advantage of a sternpaddle setup can sometimes be a more streamlined hull design or improved maneuverability depending on the specific implementation. However, they can also present challenges in terms of accessibility for maintenance or potential for damage if the propeller strikes submerged objects. The specific benefits and drawbacks are highly dependent on the boat type and the exact sternpaddle design.
