alt Hacker NewsAlong these lines wouldn’t it be better to require ships to add some forward facing underwater radar to watch out for whale strikes? Or am I missing something here?

Even if they could watch out there is very little most merchant ships or cruise liners could do if a whale crossed their path, it takes too much time to alter course or stop.
Radar is ineffective underwater because the radio waves are absorbed by the water. That is why there's no radar in use on submarines.
Sonar is not a valid solution here because it annoys the whales. Or at least high-power sonar, as used by the military, does. It would defeat the point.
