The prompt

Download workflow
Create a photorealistic photograph of the motor yacht from the input sketch, sailing on open sea, captured in full side profile with the camera at water level. Build the vessel with the structure shown in the input sketch: a long low hull; one tall mast stepped forward with a small cross-tree platform near its top; a wheelhouse superstructure with an open bridge wing just behind the mast; a midships deckhouse carrying a row of four rectangular windows with a lifeboat stowed on its roof; a rectangular funnel behind that deckhouse; an aft deckhouse with a row of three rectangular windows and a second lifeboat above it; thin railings along every deck edge; the hull side pierced by one small square window at the bow, an upper line of five round portholes on the raised forward section, and a lower line of nine round portholes along the main hull. Paint the hull black, the superstructures and the mast white, and the funnel yellow. Set the yacht broadside on a calm deep-blue sea with a low gentle swell and a thin white wake trailing from the bow, the straight horizon crossing behind the funnel top, under a clear sky with soft scattered clouds; sunlight from the front left lights the white superstructures and leaves a bright reflection path on the water beside the hull with a soft contact shadow along the waterline; the entire vessel fits inside the frame with open water in the foreground and sky above.

Notes

Qwen's own example from the Turbo model card, prompt included. The card runs it from a 3200×1120 sketch; here the sketch is scaled to 1760×608 and the canvas is 1024×1024.

Both models gave a black hull, a white superstructure, a yellow funnel and lifeboats. I did not count the windows and portholes.
