You are going to be going upwind. If you intend on sailing the distance is going to be about 20nm, if you are motoring or motorsailing it will be shorter - between 10nm and 15nm. Depending upon conditions and the boat you are in, I would not expect to make it in less than 3 hours, including the time needed to depart Nanny Cay and set set, then to get a mooring ball at Marina Cay.
