Steve,
I mounted mine outboard (port or stbd, personal preference), where the upright post of the stern pulpit meets the top rail. Out of the way of the catbird seats and steering from the rail, but still readily available if needed.

Mine is tied at the starboard jump seat, partly to the lifeline and partly to the stern pulpit. I guess I should clarify that mine is outside of the pulpit/lifelines.

Mine is mounted inside the cockpit on the aft railing between the swim ladder and aft stay. Its pretty much like no-man's land and no one sits there. It stays protected and give a cushion to lean against when at the helm.
