Time to move on so we set sail west - we had intended to go a bit further but when we got to Isla De Caja Muertos (Coffin island) the water on the west side was calm and no one else was there so we decided to stop in some nice clean water, have a snorkel and finish cleaning the bottom of the boat as we didn’t do the keel last time. As we anchored turtles popped up, when we snorkelled a nurse shark swim by only a few meters away and a ray swam under us while we were cleaning the boat.
