But when a User instance wants to check who else is on the boat, there's a condition that asks if that user has permission see everyone on the Boat, or just certain people on the Boat. If a User can see everyone, the normal dea...

I have several actions that are protected by filters that check for logged_in? and admin? and spit out 401 or 403 errors respectively if the tests fail.
