Chilean Ships for 1939

...and a last 1938 ship which I haven't posted yet.

1939 New Construction
Only three ships larger than 100 tons will be laid down in Chile in 1939. The first of these is the 4,700-ton training vessel Esmeralda, which will take over duties as the ceremonial flagship of the Armada de Chile. Due to the importance of the name Esmeralda to the Chilean Navy, the ship is very strictly designed to be a complete noncombatant and a goodwill ambassador for Chile. As such, it is a four-masted sailing barque based on the design of the German "Flying P-liners", such as Padua, Pamir, and Passat, but like the P-liners differs slightly in many small respects.

The other two ships to be laid down in 1939 will be the ocean tugs Katalalixar and Los Flamencos.

1939 Continuing Construction
The carrier Libertad will continue construction in Talcahuano.

1939 Refits
Eight escort destroyers (Alphabet-Ds) and the aviation cruiser Hyatt are scheduled for refits in 1939.

[SIZE=3]Piloto Pardo, Chilean Icecutter laid down 1918 (Engine 1938)[/SIZE]
In late 1938 Chile will be purchasing this ice-cutting steamship out of civilian service, and rebuilding it into a patrol vessel for the southern fjords. The original ship, named Aconcagua, was civilian owned but was on the list of "wartime use transports". It's likely the armament will actually be 4x110mm or 3x110mm when the work is finished.

It should be noted that this vessel is not an icebreaker, but an ice-cutter. She has extensive ice-strengthening but has a clipper bow. Her past career is delivering supplies to southern ports, which required both moderate icebreaking capabilities but also excellent seakeeping. She can cut thinner ice with her prow, but for thicker ice, the ship has a specially-designed stern which is more effective.

ALVAMA has very kindly drawn up the Piloto Pardo for me! :D Ain't she a beaut?

Secondly - would anyone mind terribly if Chile refitted the Pamir as a sail training ship in lieu of building a new vessel? Or should I stick to a new-built ship?

Go for the refit...for some reason, I think it needs a mainmast...
