Help making overlay or if anybody has one I could use please

Hi. I’ve searched 100s of pages on pixels and pixabay for a good boat overlay . I’ve found non :pleading_face:
But I have found a good background I could use. Then thought I could use a section (shown in picture) as an overlay for close ups with character behind. Wondering if anyone can help make this into an overlay :slightly_smiling_face:
Or if anyone has an overlay I could use ? Similar style boat . Like an old fishing boat
