Bauhaus Geometric Poster of a Sailboat Regatta on a Blue Bay

Five sailboats with bold triangular sails race across a calm blue bay toward a small harbor pier, drawn as a Bauhaus-style geometric poster built only from circles, triangles, rectangles, and straight lines. The sails are flat primary red, yellow, and black triangles, the hulls are slim black and white trapezoids, and a large red-orange sun circle sits low on the right above the horizon. The sea is layered horizontal bands of cobalt, navy, and pale blue, with small white semicircles for waves, and a few thin diagonal lines suggest wind. A simple white pier of stacked rectangles extends from the left edge, with a round black buoy in the foreground. Off-white textured paper background, crisp hard edges, flat colors with no gradients, subtle screen-print grain and slight ink misregistration, strong asymmetric balance and generous negative space in the sky. Modernist 1920s design spirit, clean and joyful. Wide landscape 16:9. No people, no text, no letters, no numbers, no logos.
