Use Image 1 as the base photo: the man in the boat. Use Image 2 as the identity and face reference: the man wearing a cap. Replace only the boat man's face with the face and identity of the man in the cap. Preserve the boat photo's pose, head angle, hairstyle, body, clothing, boat, water, surroundings, background, lighting, framing, and every other detail. Do not transfer the cap or any clothing/background from Image 2. Blend the face naturally to match the target perspective, expression, skin tone, and lighting, with realistic skin texture and seamless photorealistic results. Make no other changes.
