I think the times are contradicting because they are for two different ferries. 1430 is for the MTCC ferry, and 1530 appears to be for a ferry branded "Tharika 2". "Tharika 2" definitely departs from near MarryBrown. Also, there doesn't seem to be a ferry on Fridays.
As for getting to the port from airport, the airport ferry will take around 10-15 minutes or so to get to Male, and from there a taxi could take you to the port near Marrybrown in like 10 minutes max.
