Bristows had a Puma splash in on a night pilot positioning trip some years ago. One of the pilots described it me as a straightforward approach and then, Bang, they were in the water.
For what it's worth, when I did them I would approach from 45 degrees from the stern. This gave me a good angular view of the whole ship, aim at the bow and the stern will be there when you arrive, plus an easy overshoot into clear air up to the last moment before the hover.
