We visited the museum during a Portugal vacation in September 2021. The museum building is located in the office of the harbour master, at the northern end of the marina. The Museu Marítimo Almirante Ramalho Ortigão focuses on fishing technology, the boats used for it and (to a lesser extent) on Portugal maritime history.
It is worth a visit if you are in the area.
For more information see the website of the Maritime Museum Faro.
Many exhibits were behind poor glass with high reflection. It was difficult to get a clear view.
