It is time for dinner but before I pay attention to that my focus and fascination lies on the Dom João de Castro Bank, which is getting closer and closer on our way to Terceira. This bank is situated pretty much in the middle of the two islands, São Miguel and Terceira. This submarine volcano has an interesting and dramatic history, which goes back to 1718. Depending on the tide status, the tip of the volcano rises to within 13m of the sea surface or in other words the lowest depth under water is 13m. We will pass it in around 4nm safety distance at 1500m depth.
As it has not shown much activity since 2012 I am positively nervous to get along with it.
