Basically straight south, across the bay, from the Navy base. GPS 31 18 24 113 32 73. If you're coming in by boat off the water first there's a smaller public dock on the right, then its the next set of docks to the right. All the main tour boats are docked at Fonatur. Its the only place to buy fuel on the water in Rocky Point, they charge a lot more if you pay in American dollars or use a credit card, I highly suggest paying in pesos. Not sure what you're using them for, I only go to Fonatur to refuel on the water, never stayed there overnight, limited space and seems too busy with the tour boats. I always launch and stay overnight at Safe Marina, and there's another marina called Marina Puerto Penasco across the bay from Safe Harbor, looks like a good place to dock overnight, but they don't have a boat launch.
