I have the distinct impression that we were specifically talking about merchant shipping at one point, but my memory being what it is, I could be wrong, and I can't be bothered to go back through the thread and see.As far as merchant ships go, I have noted before that 'typical' merchant operations are not the only vessels that have to be considered.
So talking of non-commercial ships, many of them will have subcraft for other purposes, and no doubt their crews will be just as pleased for such subcraft to have a secondary purpose as lifeboats. But with the possible exception of military ships, I strongly doubt that any of them will spend money and volume on lifeboats with no other purpose.
Now, if I was a billionaire, I'd probably want my yacht to carry a jump-capable lifeboat.
