There are rather a lot of small ships operating in the waters south of Puerto Montt towards Cape Horn.
Many of these are serving as small roll on roll off passenger ships and ferries such as the ones crossing Canal Chacao between mainland Chile and Isla Chiloe. Many are carrying cargo to outlying settlements and remore islands.....
Both these types are what I would call 'landing craft' or 'landing barges' and in spanish are called 'barcazas' or simple translation .. 'barges'. However they would not fit in the Shipspotting 'barges' classification.
Many of the others are what at first glance most would call simply 'coasters' ... in fact many are coasters that have been inported from Northern Europe. However there seems to be no 'coaster' category nor one for ships serving the fishing industry and in Chile they are simply classified as 'motor naves' or motor ships.
So.... how should these photos be classified?
To get an idea of the numbers of ships involved just in the fishing trade lookee here...
