My sympathy's go out to the families of those who are missing, however commercial fishermen can have a FREE lifejacket if they apply.
The lifejackets are made for fishermen who are working all the time so they are made to be as comfortable and with easy movement/access when wearing them.
If nothing else they will bring a body to the surface which allows families to have closure, otherwise the 7 year rule will normally kick in which could bring financial hardship to those at home.
