A vessel has to load bunker fuel-oil at Puerto Armuelles (9471) on the afternoon of 13th May. What is the earliest Zone Time on the mid-morning flood tide that she can pass over a shoal on the approaches to the bunker berth, which has a charted depth of 9.5m? Her draft is 10.4m and she requires a minimum of 1.5m UKC.
