This link from what appears to be an Iranian source has a video which shows much more of the surroundings. It does not show a full panorama, and is being filmed from an Iranian boat, so that boat could be heavily armed. But if so it is still a small boat, given the totality of what you can see in the video.
I'll defer to your expertise, you may be able to determine more about the situation based on your knowledge of boat motions, sizes, etc.
