A green-hulled monohull sailboat with a white main sail unfurled is underway on deep blue, choppy water

A green-hulled monohull sailboat with a white main sail unfurled is underway on deep blue, choppy water. The sailboat's hull is bright green, and its deck and cabin superstructure are white. A black mast supports the white sail. No individuals are visible on board. In the distant background, a low-lying coastline stretches horizontally across the horizon under an overcast sky, transitioning from light blue to grey. The distant landmass features a light-colored sandy or beach area, backed by a sparse line of green vegetation and scattered structures, possibly residential buildings. A slender white tower-like structure is discernible on the distant shore. A green navigation buoy is present in the mid-distance water to the left of the sailboat. A small, white, unidentified boat is visible further in the background, to the right of the main sailboat. The scene depicts maritime activity in the vicinity of Port-Louis, France.
