The situation in the second video between the racing boat seems an honest accident. Distance and issues of parallax would make it easy for such a mistake to occur. The sub ramming the surface vessel in the first video seems inexcusable to me, as none of the difficulties present in the second video exist, so it is both a failure of simple courtesy, as well as a violation of the rules of navigation that brought about that first video sinking.
Still, it was interesting to see such drama on the "High Seas" Raphael ... so I thank you for adding those videos to the collection!
