New Gran Colombian Ships for 1913

[The Rock Doctor]

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.

The Rubi class tenders primarily built with submarine support in mind; existing tenders built by the then-Island Commonwealth Navy are small, old, and not really adequate for the task.

Of note, the tenders employ refurbished machinery stripped out of the protected cruiser Puerta Espana.  A 20% refit cost to the machinery has been factored into the building cost of the ship overall.

I would be delighted to show you a picture of the ship, but would first have to understand what the fuck Photobucket has done with their uploading applications.

Anyway - two units planned for 1913 and a third for 1914.

[The Rock Doctor]

The Saint Thomas class protected cruisers (yes, the first one is a Jamaican unit) are designed to operate as screening units for the armored cruisers Warrior and Matador.  They are larger and faster than previous Gran Colombian protected cruisers, but follow the same general design philosophy.

The main battery remains in single mounts, as Gran Colombia is not yet satisfied that an eight or ten gun ship with twin mounts is any better than a small armored cruiser with turreted 194mm guns.  Seven singles offers a decent broadside, even if forward and aft fire is more limited.

The Gran Colombian program to research Fire Control is well along, but running into some difficulties that delay it; the class is designed to include fire control directors, it's just a question of how far along the ships will be when the guys in the white coats finally figure out what they're doing.

Again, I'd post a pic except for some issues with Photobucket.

With lay down date of 1909 I take it that the PC's are finished by now?

[The Rock Doctor]

Negative - a mistake on my part.  I shall edit...

[Borys]

probably not enough centerline space for 7 guns.
The Japanese fitted 5 plus two wing guns.
Although superfiring probably saves you enough space for another gun.

[The Rock Doctor]

I noticed that about the Japanese ships (and later British cruisers), but my drawing looked okay.  If I can figure out Photobucket, I may even let you see it.

Apparently, I can sort out Imageshack.  Thanks for the link, Korpen.

The passenger liners Espiritu de Neuvo Granada and Spirit of the Island Commonwealth are being funded by the Gran Colombian government, under terms of an agreement with the Santa Maria Line, which will be the owner and operator.

The ships are designed for peacetime use on the Cartagena - Cadiz route, making seven day runs at crusing speeds of twenty-five knots.  In this role, they can embark 500 passengers in first class, and fifteen hundred in cabin.  Two thousand tonnes of cargo can also be stowed.

In wartime, the ship can be used as a high speed transport.  A four thousand marine landing regiment and its equipment could be embarked and landed.  The ship is designed for a strong defensive armament, but obviously this will not be carried in peacetime.  This is the reason Santa Maria Lines is not funding the ship - they're not keen on having it yanked off a lucrative schedule for risky combat operations.

On a design note - the fifth funnel is a dummy.  The designers thought it would offer a more unique and visually balanced appearance.

      - Above water (accommodation/working, high = better): 225.0 %
   Waterplane Area: 44,637 Square feet or 4,147 Square metres
   Displacement factor (Displacement / loading): 167 %
   Structure weight / hull surface area: 117 lbs/sq ft or 572 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.94
      - Longitudinal: 1.63
      - Overall: 1.00
   Hull space for machinery, storage, compartmentation is excellent
   Room for accommodation and workspaces is excellent
   Excellent seaboat, comfortable, can fire her guns in the heaviest weather

Fuel oil is still too expensive for commercial operations. Columbia has coal, stick to that.

Not that I think it matters but 1950 lay down date?  Over all very nice...

25 kts is too much. 22-23 kts OK.

I sometimes forget to change the hull date, since it affects nothing sim-wise.

I see my assumptions about fuel use and speed are not borne out by historical fact, so will tinker with the design as a slower coal burner.
