Miscellaneous weights 75 mines
You don't need the belt armor. If she meets even a destroyer she's toast.
The armour is for the stability as is the reciprocating engines
If you want stability increase the beam. 75 mines is a marginal load at best.
Trim is also very low, should be between 30 and 70.
Also, the stability is low as SS2 thinks all the misc weight is on deck level. If misc weight is a lot compared to displacement it causes imaginary stability problems so you could ignore it - stab 1.1 should be fine.
Mk2 same idea slightly improved design

I'd delete the armor belt and half the armament, as a start - this is an auxiliary.
I think the ship is too small to effectively support your major fleet elements. On the other hand, if you convert half the cargo space into accommodations, perhaps you end up with a useful depot ship to support smaller patrol units.
ok v2 as i said not fish or fowl intended to proving militry/secure goverment cargo transport [ie change of garison and goverment cargo to the Chagos Archipelago teritory] insted of hireing merchiant ships
and supply of firanjan ships
so part depot ship part transport
the armor belt is to represent reinforcement to the hull to protect aganst acidental damage

That explanation helps - but I'd still lose the armor and some guns. It seems like an alright ship for the task you outline; have a peek at my Senora Maria class packets for my own take on such jobs.
Are those 1950 layout dates correct?

Are those 1950 layout dates correct?
No, but at the same time it is pretty irrelevant, as the only thing that really change weight with year is the engine, and the engine year is correct.
I believe the year also affects armament in some way ...
Certain types of guns have a minimum design year - you can't label SS guns as 'automatic' before 1930-something, frex.

[can i combine fast ship and civilan ship rules or not?]
what say the gallery?
You may build any ship you want under the destroyer/torpedo boat architecture, provided it meets those rules. That means faster than 20 knots, and with a light displacement at or below the maximum technology your nation has obtained. Right now, that means no bigger than 1500t, assuming you've accomplished the 1500t destroyer/tb tech. So, no, this ship would not yet be legal.
Faster than say 28kts, rather (unless it is a, say, 150t boat).
Destroyers/TBs are naval ships, so no civilian construction here.
QuoteDestroyer and TB architecture - Top speed no less than 20kts, composite hull strength > 0.49
From: http://www.navalism.org/index.php?topic=81.msg1132#msg1132
Again the usual proviso about a rule maybe needing changing applies here.
There is no clause (that I know of) about ships built to civilian rules not being built to the DD rules. I agree with you though that there should be no "civilian discount" for a ship built to the DD rules. So I suppose this case is covered by this clause:
Quote
Moderators have may require a ship to be built to normal military standards if they believe that the intent of a design is to produce a cheap warship.

or maybe this clause:
Quote
Hull Strength
Minimum 0.50 cross-sectional hull strength for ships built to Destroyer/TB tech; otherwise, composite hull strength of 1.00 is recommended. Ships not meeting this criteria are at risk of moderator-inflicted incidents.

So along those lines a warning: I have it on good authority that ship-eating giant squid inhabit the waters off Darwin ;)
the shiis more theory than any thing solid
same with the question[can dd/tb tech aka fast ship tech be combined with civilian standerds
towards some thing like this
(http://www.group-trotter.net/images-t/123_PAGE-A.jpg)
well not quite but you get the idea
well it looks like the tech is not quite able to pull it off yet any way

Since when 20kts counts as fast ship?
It irks me because the only reason for the 0.50 cross-sectional strength is the too heavy engines.
That would save you like 300t on an 1000t patrol boat which need not not go faster than 20kt. More than whatever the engine themselves weight (~200t) which is absurd, and cannot be justified by 'the use of light scantlings' or whatever.
SS2 deals with single displacement hulls only and cannot be used to sim fast multihulls. 25kts is within the limits though. And L:B of 8.6 is too slim for a multihull.
The SS2 would be acceptable for a "conventional" fast transport/auxiliary commerce raider.
Your misc weight adds up to 695t BTW.
My guess is to account for coal fuelled reciprocating engines in that case 20knts is fast[ish]
Opps on the misc weight I make it 660 which is still not right
The picture has not got any thing to do with the sim its to illustrate the idea
right this should be the corect Miscellaneous weight
