A rear view of a luxury yacht at night, sailing on a calm sea. Focus on the aft deck featuring a panoramic window, lounge furniture, and warm, ambient lighting. Main deck obscured but implied with two rectangular structures suggesting shower and equipment rooms. Above, the sun deck is visible with chairs, tables, and luxurious decor. Emphasize the yacht's sleek design, warm lighting, and the tranquil, starry night sky reflected in the sea. Use cinematic lighting and composition.
