Tucupita Class
The Tucupita class torpedoboats were the last such ships to be built with reciprocating engines rather than turbines. Now on the verge of obsolesence, it's been decided to undertake a very modest refit to extend their lives and make them capable of retaining a basic harbour defence function.
Apart from the basic refit, the changes are limited to replacement of the armament: the eight (!) guns of three different calibers are replaced by a single 76.2 mm and two newer-model 47mm QF guns. The two single 457mm torpedo tubes are replaced by a new triple 533mm carriage. Aft, the weight/space savings resulting from the downsized armament is used to install two racks of six depth charges.
The class was refitted in the first half of 1913, and is expected to be in service for several years to come.
Top view is as completed; bottom view is as refitted. Sim is as refitted.
(Note that the class was original design for N2 in Springstyle, hence the odd choice of engine power)

Havoc Class
The design history is a bit quaint; it was originally a GC design intended to supplement the Battle Fleet's torpedo forces. However, the priority for torpedo forces is now to replace the earliest, small and somewhat flimsy IC-era torpedo-boats retained in post-amalgamation service. Jamaican naval shipwrights have analyzed the design, and made the modifications necessary for domestic production.
Whereas the Gran Colombian design would have fielded a pair of 100 mm and three 65 mm guns, this design features five 76.2 mm guns, plus two banks of torpedoes. One gun is forward, two abreast the funnels, one aft of the funnels, and one at the stern. The torpedoes sit between the midships and aft guns.
Havoc and Ibex differ slightly from their sisters in that the midships 76.2 mm gun has been omitted in favor of a wireless shack to allow better coordination with larger fleet units and shore commands. Havoc's design thus adds 5 t of miscelleaneous weight, 0.01 seakeeping, and is $0.1 less expensive than her sisters.
The design posted below is for the standard units; Havoc and Ibex can be posted separately if requested.
Note: the class is somewhat based on American "Flivver" type destroyers of ~1909. Thus I'm happy that the armament and three screws can fit on the hull.

Monte Patria Class
The precise circumstances leading to the construction of this quartet of vessels by the CSA for Gran Colombia are unclear. What is known is that the Assistant Naval Attache at the Colombian embassy in Richmond received an unexpected promotion within days of the contract signing, and found himself with a swank new torpedo-boat command in the Pacific.
As the Kuracki class torpedo-boats are already on the way for riverine operations, the destination of the boats is not yet certain. Speculation is that they will deploy to Coquimbo, with three boats used operationally and the fourth as a training vessel for local recruits.
The class is likely to be re-armed with 76.2 and 47 mm guns and 457 mm torpedoes upon receipt in the latter half of 1909. A re-sim will be posted at that time.
Credit for the drawing and design go to Carthaginian, and no, that's not the GC naval jack in the illustration.

Quito Class
This is the first thousand tonne torpedo-boat design for Gran Colombia. Its seakeeping is certainly not great, but the other features are satisfactory.
Of note, the class will be the first to mount depth charges, a dozen being reckoned as more than enough to sink a submarine. However, you won't see them in the drawing.

Santa Isabel Class
The S-Class torpedo-boats are improvements to the Q/R class boats built in late 1912 and earlier in the present year.
The hull is longer, and the stern more rounded, making it easier to roll ordnance off the end of the ship. This is no small concern since the class is fitted not only with depth charges but also a modest mine-laying capability.
The increased length also allows for increased bunkerage, while retaining the same speed on the same powerplant.
Above-decks, an increase in deck space and a deletion of the hoists used in for the previous class' main battery (belatedly deemed unnecessary for the size of gun) allows a fourth gun to be fitted, in the place of the anti-airship gun. This, in turn, has been relocated to a position between the second and third funnels, on an elevated platform.
Other features include simplification of the midships deck break, elevation of the first pair of boats to the forecastle, and movement of the second pair of boats slightly inboard - the latter two measures being taken to protect the boats from waves. Fire control and a short-range wireless are built into the ship.
Barring abrupt changes to shipbuilding philosophy, it is expected that this will be a standard model for GC TB construction until the next generation of turbines is available.

Tulua Class
The T-class torpedo-boats will, eventually, operate as a squadron. For now, however, their intended purpose is to function as a leader of other, older torpedo-boats, in the place of the older protected cruisers that are due to be retired. To this end, they have long-range wireless and limited flag facilities.
Construction will be limited to one unit per half-year for the moment, as the big capital ships are sucking up the majority of the Armada's budget.

Ustupo Class
The Colombians haven't built any coastal torpedo boats in several years; they've generally taken the view that old torpedo-boats can do the coastal defense job that smaller new ones can.
Geopolitical considerations are now causing the Colombians to reconsider their position. Smaller, more effective boats might be more appropriate to certain environments. Therefore, a single U-class boat will be constructed and used for trials and training, at least until such time as any additional orders might be made.

Space - Hull below water (magazines/engines, low = better): 185.7 %
- Above water (accommodation/working, high = better): 86.7 %
Waterplane Area: 7,333 Square feet or 681 Square metres
Displacement factor (Displacement / loading): 60 %
Structure weight / hull surface area: 28 lbs/sq ft or 138 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.51
- Longitudinal: 0.84
- Overall: 0.53
