What does inshore mean?
Inshore means toward the shore or close to it, especially when a boat or ship is moving or situated near land. It is common in maritime and nautical speech: a vessel may head inshore to avoid rough weather, take shelter in a harbour, or approach its destination. The word can function as an adverb, as in “the boat turned inshore,” or as an adjective, as in “inshore waters.” Its basic contrast is with offshore, which refers to being away from the coast or moving out to sea. Inshore is more specific than a general reference to being near land because it traditionally evokes travel by vessel and directions relative to the shoreline. In ordinary non-nautical writing, it may still be used for coastal routes, locations, or activities that occur close to shore.
Toward or close to the shore, especially when travelling in a boat or ship.
"The ship sailed steadily inshore toward the harbour."
Chiefly used in maritime and nautical contexts.
Situated close to the shore or in coastal waters.
"The harbour provides safe anchorage for inshore vessels."
Often used of vessels, routes, waters, or winds near the coast.
Inshore is the nautical opposite of offshore: it points a vessel back toward land, usually because of changing weather, safety, or an approaching destination.

Where does inshore come from?
Inshore was formed in the 19th century from the prefix in- and the word shore, following the model of words such as inland. The development reflects its original nautical sense of moving or being directed toward land. The root also appears in related formations such as ashore and shoreline, as well as in the older related word shore.
