Yes, that’s right. The 90 day round-the-world trip was good experience but the training is the weak point. In clear weather most situations require a mix, typically maybe 80% visual and 20% radar/ECDIS.
Trying to manage the switch (from full dependence on screens) is like taking off the training wheels. Be helpful if new mates had a little more simulator time. For a few it doesn’t take much for them to “get it” Confidence that it’s doable is the key.
