Marina Cay is closed so I would not depend on the mooring quality. Trellis might be your best option or return to Scrub and enjoy the resort for your last night.
We were at Marina Cay in Feb, moorings looked maintained and in good shape. I want to say the fuel/water dock was in operation....the old gentleman who had always run it was still there although hours were reduced. I think he must own and run the mooring operation too. I second the recommendations for Trellis as well.
