Drawing Deckplans

Is there a general rule of thumb that others use when drawing plans to better represent the displacement tonnage of a ship? For example, on the published deckplans a stateroom takes up 4 tons, but on the drawings it is only shown as 2x3.

So I'm trying to come up with a good rule of thumb to adequately display space on a deckplan vs. the displacement tonnage that is recorded in the design.

I know there is a +/- of 20% for deckplans, but what do others think?
 
The stateroom variance is typical as the 4 tons includes hallways, life support etc. related to living spaces... if you add things up the 'missing' ton is typically accounted for (and then some).

Yeah, I always assumed there was life support equipment, etc taking up part of the space. Bridges are the same, as you don't see all the gear and equipment that make up the controls of the starship in the 40tons.

But it still goes back to my original question... should two 1.5sq meter equal 1 displacement ton?
 
I use a simple 1/2 rule. All components listed in the build are 1/2 the actual item and 1/2 general access to and around said item.

So the 5ton of jump drive is 2.5tons of machinery and 2.5tons (collected with the other engineering items) of access to repair and maintain and monitor, including items like workstations, tool lockers, airlocks and whatnot as the space allows.

I never really liked the +/-20% rule, especially as abused as it often is. It's lazy at best imo. And rule breaking at worst. Would you allow me a +/-20% on my rolled stats for a character in your game? ;) And of course when was the last time you saw someone choose the -20% end of the scale? Right, never.

Yep, that's the long held standard, with 3m high total deck to deck clearances. With some variances, like TNE with it's 2m x 2m = 1ton with 3.5m deck to deck height. Either 13.5m3 per dton, or 14m3 per dton.

That was your question? (sorry, didn't read that way...) :?

Most definitely - more precisely, the 2 squares is based on a 2 square high volume. At 1.5 m per side per square that equates to 13.5 cubic meters (which is close enough to L-Hyd metric 'ton' for me). For us backward Americans, 1.5 meters also nicely equates to about 5 feet (4 feet 11 inches).

The 3 meter high (~10 foot) average deck plan height seems reasonable in order to accommodate decking, structure and essentials ('ducting' and 'plumbing').

With far-trader on the +/- 20% cop-out opinion...
 
I'm in the process of treaching myself Cosmographer and was using the spreadsheets recently uploaded to play around with some design specs - hence I was looking for more info on adequately drawing deckplans.

I've always thought that there were some things missing from deckplans, even though things like galley's, mess rooms, storage areas and the like are 100% necessary for playing the game. But to me they have always added more flavor to the game. Which is why sometimes I bitch about the "official" designs not quite reflecting "reality" - YRMBDTM (your reality may be different than mine!).

Some things tend to get left out, medical bays for example aren't even defined. Then there's stuff like airlocks that need space on the deckplans but isn't allowed for in the tonnage (for the initial one).
 
I've got CC3 with Cosmographer. It's got some nice symbols, though right now I'm challenged in getting the damn grid laid down first! :)

But it has lots of neat symbols already which, once I get the hang of things, should make for shome hopefully nice deckplans.

I've been thinking about how to handle things like sickbays and the like, and most likely will just allocate tonnage for them. Of course, it would only be on larger ships that you will see some things such as that.

I plan on starting off with a line of merchant ships, very basic, with differing tonnnages up to 2000 tons. I've got the basic idea already, mostly a large, flat and ugly rectangle optimized to move cargo only, as cheaply as possible. As far as fuel goes, I'm going to be adding in half-height decks above and below the cargo area to store fuel. So it really won't appear on the deck plans, but when I do the side view there will be additional height in it. Kinda like this:

************* Upper hull
XXXXXXXXXXX 1.5m high fuel 'deck'
OOOOOOOOOO 4m cargo deck
XXXXXXXXXXX 1.5m high fuel 'deck'
************* Lower hull.

I've done some pencil and graph paper views, but my old drafting skills are a bit too far in the past for me to draw nice oblique and other views. Maybe one day I'll work my way up to the nice 3d visions that I've seen here. someday... :)

I totally agree, and in fact CT did address this to a degree. The 1/2 guideline I use is built on the official deckplan guideline for allocating stateroom tonnage from there. Where it is stated* that half the tonnage is the actual room and the rest is for hallways and common spaces. Spaces such as galley, mess, lockers and so on. Up to recreation facilities and such on large ships. Properly laid out you can have quite luxuriously appointed large ships without cheating the tonnage.

* but sadly not well implemented in official deckplans

Further CT Book 5 HG also included other features to be placed in the stateroom allocation. Military ships would have armories, training rooms and so on. Sickbays were also mentioned. None of which had stated tonnage or costs, being simply part of the amenities of staterooms.

I simply applied the 1/2 rule to the rest of the ship features except vehicles, sub-craft, cargo and fuel. But even there vehicles and sub-craft are not full rated tonnage and include some access space around them. Likewise standard shipping containers are rated for the stated tonnage but include some space around them to permit moving them and restricted space to squeeze between them. Fuel is generally ignored in my deckplans, used to fill hull voids to permit optimal use of space while maintaining a desirable hull form. I try to estimate the fuel tonnage close though but don't sweat it much.

So Engineering not only gets the drives (1/2 the tonnage) but also the room to get to and around them, as well as isolation airlocks, tool lockers, repair bays, control stations and so on. Minimal on small ships of course, but quite extensive on large ships.

Ditto the Bridge allocation which after 1/2 the tonnage for the actual bridge workstations (at 1 workstation per ton including access) and displays and such leaves 1/2 the tonnage for access to the bridge, airlocks, ship's lockers, standard gear, sensors, commo, and whatever, including attitude control thrusters, landing gear, and so on.

I keep meaning to update my old 1/2 deckplanning guide. Maybe I'll do it for MGT. If I can muster the interest and time.

Best advice, do what looks right to you, lots of people will appreciate it, and lots will give you grief over every little nitpicking item. Sometiems justified. And odds are good it won't please everybody all the time no matter how exacting you attempt to be and you'll always forget something if you try to specify every little piece of gear... unless you really want to approach it as a real build.

Oh yeah, and my quip about nobody ever using the -20% option for deckplans. Actually there are some instances I seem to recall. Some vehicles and small craft coming first to mind. The iconic CT Fighter for one. The air/raft for another. Both depicted at more like -50% of the stated tonnage. Hence my allowing them to be stated as full tonnage but (generally) being only 1/2 actual vehicle/craft and 1/2 access. But that's me, it won't satisfy everyone. Again do what works for you.
 
When I draw deckplans, I allocate the stateroom tonnage as follows (per stateroom):
2 tons actual stateroom
0.75 tons Galley and Standard Medlab
0.25 tons Ship's Locker
0.5 tons Life Support
0.5 tons Corridors

The same stateroom stats can be used for a single-occupancy stateroom, a double-occupancy stateroom or a single berthing unit in barracks. Most single-occupancy staterooms can be re-configured into double-occupancy staterooms with ease and most double-occupancy staterooms can be re-configured into single-occupancy staterooms; barracks are not re-configurable.

I allocate the bridge tonnage as follows:
50% Actual Bridge
15% Avionics/Comms
10% Airlocks
25% Landing Gear, Docking Equipment and Fuel Scoops
