Small Orange ships and MWVs

[Korpen]

Even the 10t sets are in  the misc weight allowance.

So why mention anything about a 5ton set if they are using 10 ton sets?

[swamphen]

...was that they come in 5t, 10t and 20t sizes.

[P3D]

A small ship intended for coastal patrol, rescue and secondary mine laying and sweeping duties. I actually have the notion to make these boats diesel-powered (2x500HP engines) adding an extra 1000nm range or 10t misc. weight, but this I rejected due to fuel availability concerns.
Range requirement is determined by unrefuelled range on a two-way travel between main Orange ports at 12kts - or between Luanda and Walvis bay at reduced speed.

Orange Korvette proposal for 1911. The better engine techs (Blessed be those dice!) allowed one more gun, and adequate misc. weight for FCS (25t) torpedoes(6t) WT (10t) mines/sweeping equipment (9t) installed. Long-range radio communication is the task of flottilla leaders (either cruisers or 1000t destroyers built later).

I believe, and therefore am probably mistaken, that the WT weight was included in the FCS weight, therefore you should have another 10t misc weight to play with.  Not bad little ship in general, although that seakeeping is eek.. :D

[P3D]

Ships with similar freeboards were no unknown of running 6-8hrs full power trials (33-35kts) in gale-force winds. There were no destroyers of similar size with higher freeboard. It is rather historical, so I don't see why it would be the problem. SS2 allows building ships with too much excess freeboard, therefore N3-verse is full with such ships which are rather miniature cruisers not destroyers - and I'd like to avoid building such ships if possible.

That is also a effect of us building them for radically different mission profiles then was historically the case.

Generally TBs here are several knots slower the IRL, but better armed and much better seaboats and more habitable.
And i see nothing wrong with that.

[Carthaginian]

Well, I personally don't understand how they will handle anything but coastal work... should they deploy in any kind of real weather, they would face all the problems that my suggested 1910/11 destroyers would face, right down to difficult torpedo launching. They easily have the poorest seaboat rating of any ship class in the N-verse; I'd see them having an tremendously hard time operating in gale force winds while doing anything other steaming fortheir lives. Seaboat quility is 'relative' after all, and SS says that .70 is a minimum for 'workable' performance... that means that they lack seaworthiness for something their size, and thus are pretty dog-gone lousy ships. Running trials is NOT requiring the ship to keep a fighting trim, and thus though it could run at 30 knots, it would be exceptionally hard-pressed to do anything but run 30 knots in those conditions... no guns firing, torps having trouble launching, etc. Lord only knows how calm the seas would have to be for the ships to actually retain any useful degree of handling.

I'd say that 'Lacks seaworthiness - very limited seakeeping ability' is a waring we should see on torpedo boats and coastal ships only... not something that's intended to go to sea. If NS destroyers were suffering from handling problems during the war with their 1.00+ seaboat ratings, these ships would be utterly useless.

[P3D]

The rules allows buiding destroyers which are anything but destroyers in name. We could even attempt to sim real destroyers with SS2, but that met the resistance of some player (you were especially against making rules anything realistic).


Carthaginian,

Historical evidence shows that destroyers with similar or LOWER freeboard hardly had big problems in bad weather. They survived like 70 degrees inclination, made 30 kts+ in gale force wind. And we have no historical evidence whatsoever if N3-verse "destroyers" would behave as SS2 predicts.

I'd rather have the opinion of the moderators that what type of destroyers they want. One that has at least looks like a real world one but slower, or one that is a slow, overgunned, over-torpedo-equipped, or having even deck and belt armor, essentially a small cruiser - obeying the letter of the rules only.

Because if I build historical ships, and be severely handicapped by it (as there are "destroyers" around with over unity seakeeping, the broadside of a protectred cruiser, etc.), and even having armor (something destroyers did not have).

The 0.50 cross-sectional strength is not really representing flimsy, weak structure that would break up in any breeze. It is necessary as DDs usually had much lighter machinery, which cannot be simmed other way (could be, actually). With lighter machinery you could sim historical (altough pre-WWI) ships with 1.00 overall strength.

[Tanthalas]

Having atempted on several ocasions to sim real DDs I have given up on that line of reasoning, they simply dont work even using Historical range and preformance numbers

[Carthaginian]

Historical evidence shows that destroyers with similar or LOWER freeboard hardly had big problems in bad weather. They survived like 70 degrees inclination, made 30 kts+ in gale force wind. And we have no historical evidence whatsoever if N3-verse "destroyers" would behave as SS2 predicts.

If we throw out the SS predictions, then we are running on W.A.G.'s, and throwing out the only system we have for determining performance. We need to stick to what we have... start saying 'well, this isn't the case for X' and the entire system starts to take a hit. Either the seaboat rating has relevance to a ship's handling related to it's size, or there is no correlation whatsoever, and no ship should be handicapped on this basis.

1 - Destroyers have a minimal overall and cross-sectional strength of 0.50 - this is to represent lightweight destroyer machinery, as realistic speeds cannot be met with keeping composite strength to 1.00.  For ships of composite strength below 1.00, we as mods reserve the right to deal out damage or even loss in heavy weather.

For this rule to work as written, then seaboat quality must have some bearing on how well the ship handles in rough seas, and thus provide guidelines for the mods to determine what degree of damage a ship would sustain during heavy weather. If one player sacrifices speed and firepower in order to get seakeeping, his destroyers should be allowed to handle better and prove more durable during poor conditions than someone that focused on these attributes over seakeeping.

If you want a boat that's fast as a thief... that's fine. I have a 750t destroyer that's very similar and has just as realistic a freeboard and it has a FAR better seaboat rating. I sacrificed DOCK SIZE to get this, but attained it on the same tonnage and cost as your hull.

You gotta give something up.
This ship would, IMO, be so prone to sustaining damage during poor weather that it would be unusable in worse than 10 foot seas and would be swamped in gale force winds almost half the time.

She's not a fleet destroyer... she's a giant harbor defense craft.
Like I said, if NS and DKB destroyers with double that craft's seakeeping rating and even higher were having 'performance problems' during the war, this ship's performance would be entirely underwhelming.

I'd rather have the opinion of the moderators that what type of destroyers they want.

WHY?
Players are building destroyers within the rules, and are grossly happy with their performance. They make them with a flavor that fits their nation and with designs that fit within the specified goals for the design.

What more do we need?
If they are different than 'reality' then so be it... this is not reality.

This ship would, IMO, be so prone to sustaining damage during poor weather that it would be unusable in worse than 10 foot seas and would be swamped in gale force winds almost half the time.

She's not a fleet destroyer... she's a giant harbor defense craft.
Like I said, if NS and DKB destroyers with double that craft's seakeeping rating and even higher were having 'performance problems' during the war, this ship's performance would be entirely underwhelming.

You are incorrect, there's no indication whatsoever that this ship won't be able to work in bad weather. Historical evidence is contrary to your assumptions, regardless of repeating them.

Your ships still have several feet higher freeboard than historical ships - even 2 or 3 feet can make a BIG difference (e.g. a 750t N3-verse destroyer having the same hull depth as a 2000t one from WWII).

Also note that dock size is not an issue with this design.
Nevertheless, I can change the characteristics to give the ship a completely unjustified freeboard just to get seakeeping over 1.00 if I have to, I will build those mini-cruisers, sacrificing only a single knot of speed.

That's why I need some Moderator input how ships with realistic freeboards should be handled - would they have a significant disadvantage over fantasy ships or not.
