Rodrigo de Bastidas Class Survey Ship

With yet another delay imposed on the construction of the Triunfante class battleships, other building projects have been moved forward to fill the gap in production.  One such project are the three Bastidas class survey ships.

Originally designed to survey areas such as the Galapagos, the class is expected now to be of use in areas such as Coquimbo, the Cook Islands, and even large extents of the Amazon. 

The class is designed for long-duration missions - thus a considerable amount of space for coal, excellent accommodation and working space, and even the use of turbines, which are expected to be more mechanically reliable.  The ships are intended to stand up to adverse weather conditions on the open ocean, so have high freeboard and a good margin of stability. 

The draught is rather low, to allow for work in and around atolls, rivers, and other shallow water bodies.  For work in very shallow or dangerous water, two steam launches are embarked.

Space has been set aside for bathymetric equipment and a science lab.  The latter would include basic equipment for embarked engineers, geologists, botanists, and other scientific personnel.  A small hold forward can either be used to store additional supplies, sample collections, or other materials as required by the mission.

Armament is not particularly significant, with one 65 mm gun aft to discourage would-be pursuers.  The ship is not intended to be in foreign waters nor caught up in conflicts, however, so her greatest defence is her Gran Colombian naval ensign - a reminder that despite her own light armament, she has many friends with considerably more firepower.

Note that I've not allocated miscellaneous weight for accommodation space for "mission specialists" - given the small powerplant and limited armament, I'm assuming I can fit them in amidst the standard crew count.

Ovejas Class Dispatch Boat

A modified torpedo-boat hull to function as a courier/dispatch vessel between Gran Colombia and its outer territories.  A minor amount of cargo and passengers would be embarked.  A large set of doors is installed on the aft superstructure, starboard side to facilitate loading cargo - hence the lopside boat arrangements.

Note:  I see that the aft boat is missing from the top view...

The power plant is unusual in that half of the boilers are oil-sprayed coal-firing, and the other half are oil-firing.  In this respect, the type would be a testbed of new oil-firing boilers.  The bunkerage is technically 45% coal as a result.

Due to the close similarity to existing torpedo-boat types, the ship is classified as a sub-type of the torpedo-boat, and follows nomenclature/numbering rules for that type despite being identified as "TD" rather than "TB".

Libertad Class Yacht

At President Alizandro's insistence, and to the Armada's annoyance (since it's coming out of their budget), Gran Colombia will be laying down a new presidential yacht for the use of the head of state. 

Libertad is equipped to provide for luxurious transportation of the First Family, a guest and his family, and a modest number of aides and staff (seventy).  There is a range of luxuries, ranging from a library to a swimming pool.  The fittings are to be quite ornate and will include originals by a number of Gran Colombian artists; consequently, the ship is expected to be considerably more expensive than a modern protected cruiser.

The yacht is not armed for surface action; the machine guns are for security, but the 47mm guns are saluting pieces only.  President Alizandro believes that it should not be necessary for the yacht to be armed in peacetime - and in a scenario where irregular forces might be at work, such as the pirates of Mesoamerica, a dedicated military escort would accompany the yacht. 

In wartime, it is expected that the yacht would function as a hospital or casualty evacuation ship.  The Presidential and Libertador Suites would be converted to operating theatres, the dining/conference room to a ward, and the smaller cabins would be utilized as required.  This is not just a matter of making the most of the yacht; President Alizandro also reckons that the donation of the presidential yacht for this purpose would help his stature amongst the common military man, plus the yacht would be relatively safe in this protected non-combat role.

Sirio Class Tug



The Sirio class salvage tugs will be built and kept on hand for emergencies; in peacetime, they may assist in civilian operations or on patrol duties.  At least four are expected to be built, at six month intervals.

The armor belts are more along the lines of reinforced hull plating, for those occasions when the ship may have to get physical with its charge.

Jose Alizandro Class Government Service Ship



The Jose Alizandro class government service ship is essentially a small, self-propelled government office. 

It was initially planned that two ships would be built; one would travel in a standard route around the Line and Marquesa Islands, while the other traveled in a standard route around the Cook and Samoan islands, bringing the benefits of the modern Colombian bureaucracy to the isolated communities of the Colombian Pacific Territory.  Successful lobbying by the state government of Amazonas del Sur for similar vessels on the Amazon led to further construction in 1915.
