There are advantages to visiting Antarctica in a small ship.
You can make a continental landing, access areas too small for the large ships, have the opportunity to make as many as three shore trips a day, walk on sea ice, climb up a glacier with an overhang, and take a polar plunge. We did all that with our 100-passenger boat through Quark Expeditions.
But even more than that, you are closer to the water and every now and then can catch a glimpse of the remoteness the explorers, whalers, and sailors felt on this continent.
