When we were equipping Enchantress three years ago, we bought Mustang. offshore auto-inflatable vests with harness for ourselves and regular auto-inflatables for our guests. We always put them on beforer we leavethe dock and we ask our guests to wear them but don't insist.
On my previous boats, when we went off shore we wore Lyracis (sp?) harnesses and used 3-point tethers so we were always attached to the boat. We did not wearlifejackets as they were uncomfortable and hampered movement. Not sure what I would do now as our inflatables are confortable and don't get in the way. On the other hand the Lyracis harness is one of the strongest and most durable made, not sure how the built in harness of my inflatable compares
