Correct. The helmsman was guaranteed to fail (in some form or other) because prior faulty decisions and orders had put him in that situation.As always, quibbles rather than engaging with the core point.
You're now declaring that this challenge never could have ever been resolved. So there would not have been a roll.
Were this a game scenario, the "roll" here would have been to see what form that failure ultimately took. And for me, the truly bizarre (and very rare!) aspect to this specific example is that, in hindsight, failure = success and success = failure!
Had he failed to turn the ship and hit the iceberg head on he would, unintentionally, have succeeded in maybe* saving the ship and almost certainly saving a bunch of lives; as even if it had sunk they would have had far more time for an orderly evacuation.
However, he succeeded in turning the ship as much as he could given the lack of warning and the ship's speed, which meant the iceberg carved a long gash down the side of the ship and in so doing, doomed it.
* - it's uncertain whether the Titanic would have sunk from a head-on collision, but if it had it would have taken a lot longer to do so.
In situations where different degrees of failure (or success) can have different consequences, isn't it still useful to roll even if outright success (or failure) is impossible, in order to determine the degree of failure?We are, I should think extremely obviously, talking about cases where a roll is in fact valid, where success can in fact occur.
Climbing a cliff that's flat-out beyond your skill is a good example. A "good" fail (i.e. high roll) might mean you don't even get off the ground, or realize very quickly you aren't going to make it; no harm done other than you're still stuck at the bottom. A "bad" fail (low roll) might mean you get most of the way up and then fall, or become stuck in place. A moderate fail (middling roll) might mean you fall only a short distance, or get stuck but in a low enough place that someone else in the party might be able to rescue you.
And sure, most game systems don't codify this sliding-scale type of roll; but IMO that's no reason not to do it.
