Inboard Meaning in Sailing

Inboard refers to anything located toward the center of the boat or inside the hull, rather than toward the outside or ‘outboard.’ It is most commonly used to describe an ‘inboard engine,’ which is mounted permanently inside a compartment within the hull, connected to a shaft and propeller. This term can also describe the placement of equipment on deck, such as ‘moving the genoa tracks inboard’ to allow the boat to sail closer to the wind. One clear example involves a sailor working on the inboard diesel engine to check the oil before a long voyage. Inboard systems are generally more powerful and protected from the elements than outboard motors hanging off the stern. Understanding the distinction between inboard and outboard is essential for communicating the location of parts and equipment. It defines the internal vs. external geography of the vessel.
