Arid islands is another favourite location if we can get an anchorage in Boat Cove, a small deep cove that is sheltered in South Westerly winds. The visibility here is quite variable from a 3 metres to 20 metres. This location does not have the large sea urchin barrens that Mokohinau islands have, but still lacks in large schools of fish that use to be here in the late 70's when I first dived this location.
