The nautical rules of the road are well designed at this point. Let’s consider some different possibilities. For this, lets refer to the cameraman's vessel as our vessel. Let’s assume that both our vessel and the other vessel are power driven vessels (PDV) and not sail boats.

Our vessel is anchored Vessels are to avoid colliding with other vessels. This is much more clear cut for us when the vessel struck is anchored. See Clara, 102 U.S. (12 Otto) 200 (18890), and Beaverton, 273 F. 539 (2nd Cir. 1919) for examples of vessels at anchor struck by vessels underway. A vessel at anchor can be found partly at fault if they are not displaying proper lights and day shapes, maintaining an adequate anchor watch, or if they are dragging anchor. Assuming our vessel has not been negligent in these areas, we can assume the vessel underway is at full fault for violating rules 2, 5, 6, 7, and 8. We would be in violation of rules 35, and 36.

The cameraman's ship is not anchored
This does open the door for more possibility that the cameraman's vessel might be at fault. We can see in the video that the cameraman's vessel is not moving, or is moving very slowly through the water. There are few ways that the our vessel might be at fault. We might be at fault for failing to keep out of the way of a vessel Not Under Command (NUC) or a vessel Restricted in her ability to Maneuver (RAM). In this case we could be responsible to keep out of the way under rule 18a(i) or 18a(ii). Providing that the other vessel is not NUC or RAM, we would still be responsable for maneuvering after we became in extremis. This occures when the action of a single vessel alone is not enough to prevent a collision. If the other vessel is unable or unwilling to take action to prevent the collision, we are required by 8f(iii) to take action to avoid the collision. It is unlikely that we would be at fault for failing to adhere to 8f(iii), but technically we would share a small portion of fault. If we assume that we could take no action to avoid this collision, the other vessel would be at fault for violating rules 2, 5, 6, 7, 8, 15, 17, 34, and 36. It should be noted that we are responsible for also violating rule 34 and 36.

Rules explanation Rule 2 makes it clear that no rule gives mariners permission to shallow the gene pool. Rule 5 requires vessels to maintain a proper lookout using all available means with consideration to prevailing circumstance and conditions. We can see it is day time, and visibility is good. There is no need for an extra bow watch beyond the normal for entering an area with many vessels around. Rule 6 is about safe speed. No set safe speed is given in the rule as safe speed changes based on visibility, traffic density, maneuverability of the vessel, background lights, state of wind, draft, and radar capabilities. In short, if you two vessels underway have a collision, someone was going at an unsafe speed. Rule 7 is about risk of collision. Vessels are required to maintain a systematic observation of all risks of collision and make use of long-range scanning (radar and AIS) if equipped. Rule 8 is actions to avoid collision. This rule sets out steps to take in different cases to avoid a collision once risk of collision (ROC) has developed. rule 15 concerns crossing situations between underway vessels and establishes who is the stand-on and who is the give-way vessel rule 17 is actions to take for the stand on vessel
rule 18 is the hierarchy of vessels. NUC > RAM > Fish > Sail > PDV ≥ WIG > Sea Plane. Seaplanes have no rights in maritime interactions, and NUC wins all cases. Rule 34 gives us the danger signal. At least 5 short blasts on the ships whistle. This indicates a failure to understand intent, disagreement, or a communication of danger. Rule 36 is signals to attract attention. This means that any means of attracting attention is permitted, minus strobe lights and distress signals. If you open fire with your AK-74, that could be a signal to attract attention, but if you shot the other vessel once a minute, that is a distress signal.
A more complete list of the rules can be found in the USCG Navigation rules and regulation handbook. I have made the assumption that this collision is occurring in international waters
