Here is a better shot of the chart. The orange boat is Vestas just after the collision while she is doing a S&R pattern and drifting down wind. She is in international waters, about 45m of depth, 10NM from the outer sea buoy and 20NM from the TSS.
It is hard to argue that she was travelling at safe speed, since the collision obviously occurred. What we don’t know is what caused the collision. Speculation on the web is that the fishing boat had AIS but was not using it. I think the mystery is whether or not the fishing boat was displaying any lights and why Vestas wasn’t using radar.
