I would imagine that a jacket packet for 'every day' people would be/is designed quite differently. I don't know how much a current life jacket weighs- maybe four pounds?- and the additional weight of an enhanced jacket might weigh up to 15 pounds, which would still be doable. My guess is that a 'private' packet would be minus the bells and whistles that the deep pockets of the military could mandate.
Commercial fishing in Alaska is a dangerous activity but even though on a smaller scale, private boating which often may include alcohol is even more dangerous. We have many communities on off-shore islands; often a tragedy starts out as a light-hearted trek on the water to the mainland.
