I am struggling to remember, and may be wrong, but the RYA used to teach round turn, two figure of eights, then round turn, then changed to the OXO cleat hitch, probably as boat designs modernised and cleats changed.
Google suggests the OXO and the cleat hitch are two different knots. The cleat hitch always features a locking hitch.
I honestly don't think I've ever seen OXOs holding an unattended boat in a marina and I'm sure almost everyone jazzes up the cleat hitch to their own taste and circumstances when used for mooring.
