We arrived at North Minerva Reef at 9 this morning. It's a 2 mile diameter atoll with the reef exposed only at low tide. There are about a dozen boats here already including several we spoke to on VHF during the passage. We are anchored on the windward side about a hundred yards from the reef. The surf crashing on outside of the reef creates a continuous distant roar. Like the sound of a jet taking off at a nearby airport - but continuous. Tomorrow we'll explore a bit and try to get some aerial images with the drone.
