With hurricane Fiona heading our way I have just checked our mooring bridle attachment and swivel.
To make this easy, even though the chain is quite heavy because it was sized for our last boat, I attach a spinnaker halyard to the bridle and hoist it up while it runs over the bow roller, as shown.
Way easier and less messy than attaching a line to the bridle and running back to a sheet winch.
Note that this only works in winds under about 8 knots since more breeze will blow the boat back and cause the bridle to jump out of the roller.
