Hmm. I believe there is a taxi-stand at Trellis - may be shared with the ferry service to Marina Cay and NS Ferry -- seems likely ( what do I know, just [censored] U ME-ing ) that on a FMP night that place would be manned and selling tickets for both taxi and ferry service. Walk down from EIS to the beach, turn left and check near the dock. IF you are needing taxi service later to your marina or charter base, you may, indeed, just get lucky.
