Some tinkering with the central section. This is pretty much by the book, near as I can tell. One side shows the cargo holds, the other shows the internal passage and placeholders for the open frame. The bottom shows a top view, and I've indicated where those bevels on the fore and aft hull need to be shortened up a bunch. Since this looks like it should work (although it won't match the square section shown in the pic), I'm going to start tinkering with the front end a bit, then try to nail down some deckplans.



Interestingly, at 4.5 meters tall, the cargo pods work out to almost exactly 60 tons, and the wide spot in the central corridor comes in at 10 tons, leaving 10 tons for internal stores and such. Still haven't figured out how to deal with the ATVs yet either...

The thing is, and it's a problem most ship designs ignore/fudge, if you put it on the nose all you get is a hemisphere view forward, you're blind to the rest of the sky. My solution (forward but below) is only marginally better giving a little more sweep.

Then again maybe that cylinder thingee is an extending boom to allow a fuller sweep?

Most ship designs just handwave a hull integrated sensor/antenna net to sweep the whole sky without pointing issues. I'd drop the dish myself but for the nod to the original

Realistically they should be in the small craft and not count towards the ship tonnage. The only way they'll get used on the ground and retrived is via the small craft anyway. It's one way out of that problem anyway

Okay, I mocked up your suggested dimensions above, Dan, and from what I'm seeing you're a bit short on tonnage.

Aft section - 10.5 x 33 * 12 (4 decks) = 4158 cu m = 297 tons
Fore section - 10.5 x 27.5 x 12 (4 decks) = 3465 cu m = ~248 tons
Center section, including pinnaces = 2098 cu m = ~150 tons

Total = 695 tons total, 105 tons short.


I also mocked it up according to the original deckplan; the two aft sections are actually a bit wider (1.5 m) than the front section when you put a grid to it. By the original dimensions, I get -

Aft Section - 13.5 wide x 12 high x 32.5 long = 5265 cu m = 376 tons
Fore Section - 12 wide x 12 high x 30 long = 4320 cu m = 308 tons
Center section, including pinnaces = 2098 cu m = ~150 tons

Total = 834 tons total, 34 tons over but still within the 10% slop allowance, and those are just the numbers without beveling the boxes on the front and back. That overage will probably go down some once that's done. Doesn't leave a lot of room to do anything too crazy with the bridge, though.


I agree about shifting some of the fuel around and spreading it out some. I found the discrepancy on the original deckplans, too...whoever wrote the text just counted the grid squares as 1 meter, not 1.5 meters. Just an oversight in editing, I would guess. But, the plans are fairly close externally, so I think I'll run with that.

As for the original CT specs, my numbers came up identical to yours (not that I thought yours were wrong, I'm just sometimes anal-retentive about these things). I added in the 48 tons of additional fuel like the text says and come up with 40 tons left. A couple of lifeboats might not be a bad idea, but I think I'll run the design thru HG Shipyard and work out the numbers for that....

--------------------------------


Interesting...the only places it it come up different is 3 extra tons of cargo and the price. I built it as a close structure, which means we could add scoops and purification plants for basically 10 tons of cargo space (73 left with scoops/purification). Or, we could build it as a dispersed structure and keep the purification plant, so it has to rely on the pinnaces for wilderness refueling, which still takes up 10 tons of cargo.

Oddly enough, HG makes most of that extra 40 tons go away quite handily. Almost like they built it with HG, then decided to go back and do the Bk2 version.

As for the ATVs, I thought about leaving them stowed in the pinnaces, but the ship is unstreamlined as written. So what do you do with them when you need the pinnaces for refueling? Probably better off keeping them in a couple of bays with airlocks big enough to mate to the pinnace...dock, drive the ATV on, and off you go.

As for the deckplans, I tend to section off areas by displacement, then work out component/access/common issues one that's done. I still use something fairly close to your method (1/2 component, 1/4 access, 1/4 common), but tend to keep the stateroom tonnage with the staterooms, engineering stuff in engineering, etc. It seems to all work out pretty close to the same.

Well, I think I've babbled enough for this morning. Let me know what you think...

Just for fun, I uploaded a set of the blank Type C I started with. Feel free to draw up your own version and share it with the rest of us.

You can download them here -
http://www.travellerrpg.com/CotI/Dis...283#post363283


For reference, the forward section is called Deck 1, the central section is Deck 2, and the aft section is Deck 3. Each section is divided into 3 decks, labeled A (at the top), B (the middle deck) and C (the lowest deck).

Happy Doodling...

Default Epiphany!

After a long nap this afternoon, I had a moment of enlightenment regarding this build. I was getting kinda frustrated and just about ready to shelve it for the time being...



I moved the turrets around a bit, rotating them 45 degrees (which took them off the top, bottom and sides, and put them on the flat beveled corners instead) and put them out on pylons for interest. I took the huge nose dish, making it into 2 smaller ones and put those on the centerline of the top and bottom. Looks okay, and best of all, completely removes the issue of weapons fire hitting the sensor dishes, and gives the dishes a 360 range.

The two orange boxes are the ATV bays (eventually, just placeholders for the moment) and the box between them is the air/raft bay. On the other side is a long skinny cargo bay (about the same size).

Deckplans are coming along as well (I tend to work the two in conjunction), and I should have something concrete in the next few days.

That works. Turrets look a bit big.

Well, the turret and pylon come in at about 3 dtons...I shrunk them down to 2 dtons and it still looks kinda big. Go with actual dimensions or shrink them down so the look a little more proportional?

Default Deckplans Ver 1.0

Okay, here's my take on the deckplans. The areas marked 'Custom space' are reserved for that extra 40 tons in the design. I'm starting to do some detail work (mainly the sensor dishes at this point) but here's a progress shot.

Deckplans Version 1.0
