Hummm....
If the northern canals freeze during the winter, can the IC military take the northern ones? If so can glacierheart be relieved like Bastogne by Patton? If the north is taken, how will it effect Clyntahn's war plans with hostile forces on the border with the Temple Lands? |

I'm really not sure where you are getting your numbers from. The 904 miles number would be for a basic 'design load' of fuel. The 1,900 miles number is for a maximum bunkage loadout. (It is nice to see that RFC remembered that the fuel economy would decrease with the higher load, and slowly increase as the fuel was used; creating a lighter and lighter ship as the fuel load decreases)

Hi Renegade13,
Given the 6' draft, and the propensity of cities to establish themselves on rivers in conjunction with land routes, the potential arises for the ironclads, especially if their muzzle-loaders are replaced by breech-loaders using cordite, the range of targets might be dramatically increased, and the prospect of cities surrendering to ironclad led invasions (marines now in powered landing craft :-) might be a feature of book number 7 or 8. Feel free to disagree, L
Any snippet or post from RFC is good if not great!

I will take a stab at explaining the difference. Mechanical devices usually have a rated or continuous rating load, speed or whatever which uses them at their most efficient output (get the most out for the amount of energy put in) but can be operated above that limit at a lesser efficiency and sometimes shorter operating life. So, these ships, after taking on the maximum amount of bunkerage (fuel) have a range 1,900 miles at a speed of 9.5 knots. Any speed above that will shorten the range. Speeds below that may or may not extend the range. The longer range takes into account that it is operating at it's maximum efficiency point and also that as the fuel load decreases it will get more miles to the ton of coal so to speak. This is not what they would prefer to enter combat with though because the increased weight of the fuel may present handling and maximum speed problems. The ideal load for combat would be 480 tons of fuel giving the ship an unspecified but much lower range due to the much higher fuel consumption required for operation at its maximum speed of 18 knots. This speed will allow them to overtake anything currently afloat with shocking ease. More than that, their attack vectors will not be limited by the winfd direction and so they will have a really serious advantage over anything that propels itself with sail. In addition, the higher speed will mean much lower dwell times in enemy kill zones while still retaining the ability to hammer them and take hits from them due to its armor. All in all, a giant step forward in naval warfare. |

After reading these posts, I have an observation concerning the name RFC has given the steam ships. He named these an "Ironclad River Gunboat of Casemate Design". However, looking at the design specs, these are capable of ocean travel and are certainly not limited to usage on rivers and estuaries. We do not know certain other nice to know details such as the turning radius, stopping distance from full speed etc. but I can easily envision these ships ranging throughout the Gulf of Dohlar and some ways up navigable waterways.
In Vietnam, I served for a time on a PBR, Patrol Boat River. Just because its name implied that it was for use on rivers didn't mean that we didn't, on several occasions, find ourselves in the South China sea, well out of sight of land sometimes in 25 to 30 foot seas as well as on the Mekong river close to the Cambodian border. It was a very versatile craft capable of doing a whole lot of things including close in shore operations support that didn't show up in the name. I don't expect these ships to be any different. |

I sincerely doubt that this vessel will ever get even close to it's theoretical Max speed of 18 (safehold) knots.
Using the displacement hull speed equation v_{hull} \approx 1.34 \times \sqrt{LWL} (from wikipedia) we find that the value by RFC is effetivly the max hull speed for the length of the ship. While this is all fine and dandy so far we now have to deal with some nasty real world issues. First power requirements increase exponentially as you approach hull speed limits. Even with help from Merlin you cannot get that sort of performance from a piston powered steam engine. You can only get close with a steam trubine that is way beyond the tech required. Secondly the low freeboard has a terrible effect on speed as in any sort of seaway other than dead calm the ship ends up driving it's nose under the breaking waves and sapping off a huge amount of power. Just compare the Royal Soverign class 410 feet,19 feet 6 inches freeboard and a speed of 17.5 knots with the contemporary Hood which had the same hull design and machinery but with a lower freeboard. 11 feet 3 inches and a consequent top speed of about 15.5 knots. The Royal navy was not happy and never again built low freeboard battleships because of the poor performance in rough seas. To give you an idea of what is plausable with the technology of the time the hull speed for 410 feet is 27 knots. This suggests that even assuming that the Howmsmyn machinery is as effecient as that on the Royal Sovereign (it almost certainly isn't) proportionality suggests that we could expect the proposed gunboat to have an effective top speed of between 8-12 safehold Knots which is still highly respectable for a ship of her size. (Yes I know these things don't scale linearly but it's a good first order approximation.) To compare to a modern ship we can take the Cornelia Marie from the dealiest catch, she is 128 feet (39 m) long, 28 feet (8.5 m) wide and with twin Mitsubishi engines generate 630 horsepower for a top speed of around 10 (Earth) knots. |

Huh, So our dear grand inquisitor has managed to create Vicarate's worst nightmare? I predict an interesting "what has gone wrong now" meeting with the Group of Four. |

I agree.
In fact this will not be the first "what has gone wrong now" meeting the Group of Four has had. I believe the Vicarate's nightmares are about to go from "simply terrible" to "unbelievly awful" in a hurry !! Myself, I can hardly wait to read about them [wink] It will interest me to see if Clyntahn is powerful enough to weather this particular storm or will it take an even worse set of news to finally sink him permanently in the <Go4>'s eyes, (enough to see him finally deposed at least). EDIT: Added Clyntahn's power phrase ?? Comments ?? R

Hi BlackJack217,
So do I! The Go4 meeting that discusses the results of Schueler's actions in Siddarmark will be fascinating if it includes Duchairn (RFC) laying out just how bad the effects on the temple revenues are going to be, Maigwair explains the major military ramifications since Charis now has their mainland ally, and Trynair on the political aspects of why it was so stupid. How quickly will the Go4 find out about the SoS etc? Will Clyntahn try to present Siddarmark as a wholly internal civil war, that he had nothing to do with? What will the other 3 do when they do find out? What can they do? How long will the news from Delferahk take to arrive at the temple? It wouldn't hurt to have the reaction of the vicar in the street, or the rest of the episcopate to all this either. :-) How safe can any leader or any country feel if Clyntahn can provoke revolution whenever he feels like it? If the Siddarmark army was the most powerful on Safehold with just pikes etc, then arming a the remaining quarter with modern flintlocks ought to more than provide the equivalent firepower, while the new breech-loaders etc would easily exceed that, even against flintlock armed temple armies. What size army was Maigwair creating for his expeditionary force(s)? How big was big enough to take Charis and Chisholm, etc? Not much, really. Given the state of the Charisian militia, it wouldn't take much aside for very limited garrison duties since they plan on killing everyone, while aside from the ICA (if its still in Chisholm), the same is true for Chisholm and the rest, if they bother attacking them at the same time, which I doubt. Does anyone believe Clyntahn would care if the temple expeditionary forces wore themselves down to nothing destroying the last vestige of humanity anywhere in the EoC, so they wouldn't return to possibly contaminate the mainland? Given the arrogance of the mainlanders, they shouldn't feel the need to match the size of the ICA if it were still in Chisholm etc, so Allyn or his staff might think they need to just match the ICA, or an even smaller fraction of it. A goal of an army of a half million would be smart in terms of training and equipping, which could be expanded if needed once it had been fully prepared, according to any changed circumstances then. I doubt an army of more than a million could be justified to Duchairn as a separate force from the rest of the temple guard and all their obligations, though Maigwair and his friends might insist on larger forces for ego reasons. Given a force of a million men, and the readjustment of regenerating the navy again interfering with Maigwair's plans to field the army, just how far along is the re-equipping of the temple guard army? Paying for even a million soldiers is something else again as discussed on other threads. Now Siddarmark could easily require orders of magnitude more soldiers to deal with it, which the Go4 can't afford. The logistics of getting to Siddarmark have been considered on other threads, and while dragons may advance part of the army up to ~40 miles a day, moving and supporting a million men will be unprecedented in Safehold's history, so disastrous mistakes are bound to occur, without any help from OWL, Merlin, or Nynian deliberately gumming up the works. We shall see in September. I've posted before that ZC may simply smile and ask the other 3 Go4 members "so what do we do now?" Given how they're tied to Clyntahn, and blaming him publically is all but impossible, the Siddarmark mess might only solidify his dominance of the Go4.

Hi lyonheart,
Nothing to disagree with there! Even before getting the improved armament you mention, these armored river-capable craft will seriously threaten any city along a river that is deep enough and wide enough for these ships to operate in. It is just that the 'threat range' would be significantly increased by the newer weapons.
