This is Argo, a yacht belonging to Seamester Global. Seamester, based in the USA, offers experiential nautical training - students spend a semester at sea, learning a wide range of skills and visiting places that they would otherwise probably only read about. Can you imagine what an amazing experience this must be? What a way to discover the world! If I had a child leaving school and considering taking a gap year, I think this would be high on my list of suggestions to them.
You can follow the activities of the students on board the Argo, by reading their regular blog posts and listening to their audio updates here.
