These debates pop up regularly.
At one end you get the people who wear a drysuit when flying 5 mins over water.
At the other end you get ones like me who take the view that a raft is the realistic civilised solution which is acceptable to "normal" passengers, and you brief them on how to use it, and the priority will be to make a ditching after which one can get out.
I carry a Survival Products raft, the
4-man non TSO version
with a canopy. I think Harry M sells them. SEMS at Basildon can overhaul it.
