[The Rock Doctor]

Bids are now being evaluated.

Entries exceeding the design maximum draught have been eliminated, as river depth can not be negotiated. 

The Congo Free State hopes to provide an evaluation shortly.

[Nobody]

The German yard are looking forward to the feedback, so they can refine their potential clients needs.

First Round Evaluation:  CFS CDS RFP

The Congo Free State thanks all who submitted proposals for the coastal defence vessel competition.

Please note that all vessels exceeding 5.0 metres maximum draft were eliminated without further consideration and are not evaluated below.

Although not previously defined in hard terms, some criteria were used to eliminate designs.  These were a lack of miscellaneous weight for long-ranged wireless, inadequate freeboard (avg. 3.05 metres) and inadequate ferry range (2,500 miles or less).  While these latter two factors are not issues while on-station, the CFS has determined they would be necessary to ensure safe delivery to the CFS and safe servicing overseas if required*.

Evaluation of vessels follows:

1.  Unnamed, Germany:  Considered unarmed for role.  Eliminated.
2.  Kongo, Italia:  Considered fairly capable for size.  Request re-do with light battery added for Round 2.
3.  CFS Congo, USA:  Considered fairly capable.  Request re-do with improved seaworthiness for Round 2.
4.  Bohemian, UK:  Deemed undergunned for size.  Eliminated.
5.  Congo II, Italia:  While improved light battery compared to previous design, seaworthiness inadequate.  Eliminated.
6.  WATCFS, Iberia:  Considered capable for size.  Advances to Round 2.
7.  Kongo II, Germany:  Powerful unit.  Request re-do with improved freeboard for Round 2.
8.  Congo, Italia:  Concerns about seaworthiness and lack of miscellaneous weight.  Request re-do for Round 2.
9.  WATCFS, Iberia:  Unique armament seems not to provide benefits.  Eliminated.
10.  Kongo III, Germany:  Inadequate protection.  Eliminated.
11.  Congo, Italia:  Concerns about seaworthiness and lack of miscellaneous weight.  Request re-do for Round 2.
12.  Coast Defence, Guinessstan:  Inadequate protection but interesting concept.  Will consider re-do for Round 2.
13:  Kongo River Bad@ss, Netherlands:  Intriguing idea but inadequate seaworthiness/range.  Request re-do for Round 2.
14.  Kongo River Bad@ss, Netherlands:  Inadequate seaworthiness/range.  Eliminated.
15.  Sentry, UK:  Unique armament seems not to provide benefits.  Eliminated.
16.  Floating Disc, Iberia:  Different.  Request re-do with one or two main battery turrets for Round 2.
17.  Kongo River Bad@ss, Netherlands:  Not seaworthy.  Eliminated.
18.  Improved Vulkan, Russia:  Not seaworthy.  Eliminated.
19.  Floating Disc, Iberia:  Powerful but expensive.  Advances to Round 2.
20.  Bombard, UK:  Insufficient anti-ship battery.  Eliminated, but would be interested in smaller, simpler models that could be assembled at Leopoldville.  This would be a separate tender.**
21.  Anvil:  Capable and competent for size.  Odd quarterdeck height.  Request re-do for Round 2***
22.  Hammer:  Uncertain of necessity as complement to 21.
23.  Gun Boat, Iberia:  Not seaworthy, no miscellaneous weight.  Eliminated.
24.  Improved Onega, Russia:  No main belt.  Eliminated.
25.  Improved Onega, Russia:  No main belt.  Eliminated.
26.  Wrath of Khan, Netherlands:  Not seaworthy.  Eliminated.
27.  USS Mohawk, USA:  Not seaworthy.  Eliminated.



*Frankly, the CFS ports at Matadi, Banana, and Boma are probably not up to anything beyond basic maintenance at this point.
**Which Belgium will contact the UK about at a latter date.
***The inclusion of a pitch was helpful in keeping this one alive.  The large miscellaneous weight is also potentially useful.

[Tanthalas]

Reworked the Kongo class, slightly deaper (still within limitations) added a battery of 3" QF guns, and increased misc. Weight to account for a wireless set and 17 tons of whatever you want it to be.

WATCFS, Iberia:  Unique armament seems not to provide benefits.
No it's not supposed to. It was purely designed to be weird. ;D Same goes for the Floating Disc designs.

Messing around with the first one to add turrets is a bit challenging when trying to retain its weirdness. I wanted two singles, but realized Iberia does not have single turrets for the 11" guns. Had to trim the ship here and there and as a result it became a little bit more expensive and in order to keep it simple, I used the empty 5th weapon slot for the 11" gun rather than to move every gun to the next slot.

Armstong would like the buyer to note that curret iterations of the Anvil design use the most mecanicly simple engines for ease of mantinence. Should the upkeep of more mechanicly complex engines not be a great worry, the design can be made more capable.

OOC
I'm assuming that means "underarmed"

1.  Unnamed, Germany:  Considered unarmed for role.  Eliminated.

Back in the German Yards the engineers are scratching their heads over the letter from the Congo.
They requested a riverboat, but it seems they actually want a battleship or a monitor like ship which can navigate a river. - So that's why they refused the protected cruiser as well, right? - Probably, but why do they request a higher freeboard of at least 3.05 meter on a ship which has 3.06 meter average freeboard? - Who cares? Just do it, alright? - Yes, yes, I will. Should I change something else? - You can play around with the design later. Just do what they want for now. - Fine, I get it.

37mm Hotchkiss

[KWorld]

The Fore River Shipyard is somewhat puzzled by the request to increase seaworthiness when it's design already has an average freeboard of 3.14m, but expects the confusion is due to the use of standard, rather than metric, measurements.  But if the customer wants more freeboard......

[Nobody]

Of course the engineers of the rejected proposals don't sit around doing nothing. One refused to accept the rejection, after carefully checking that his design does indeed meet all official requirements (freeboard, range and misc weight) he sat down deleting the criticism.
Well, he thought, if they think - that a protected cruiser is not sufficiently armored - then they should be interested in a Armored Cruiser.
