We anchored at Isla San Geronimo. The anchorage is 30' in weed off the fishing camp on the south east side of the island. Approach from the east to avoid the reef extending from the south end of the island. Charlie suggests that San Geronimo is one of the better anchorages north of Turtle Bay.
While we were there the winds in the region were very light northerlies with a 1m NW swell. We had some trouble setting our anchor, I believe because the Bruce doesn't like weedy bottoms. There was light swell in the anchorage and when the wind died entirely overnight we sat beam to the swell and rolled. This, along with the sound of the surf breaking on the island made sleep difficult. If I had to make the trip again, I would skip San Geronimo and travel directly from San Martin/San Quentin to Cedros, which Charlie reckons is 141 nm.
