Just got my book, and for some reason I'm fixated on seeing how the cargo, passenger, and vehicle bays all mesh together. I've just skimmed, but can't find some answers.
How much cargo does one Space give you? I can't find it anywhere in the design rules. I see suggestions above of .25 tons per Space, but where was that stated? I had assumed it was .5 tons per Space due to reversing Shipping Size = .5 tons per Space. The 9 Space Ground Car in the example on pg. 53 doesn't mention any spaces at all allocated for cargo in the design break down. But, it lists .5 tons (2 Spaces if .25 tons each is correct) in the description.
Most of this works for me. 1 Passenger = 1 Space as default, but can double or triple (imagining cargo net seats from my military days) for up to 3 Passengers per Space. Sleeping bunks are 2 people per Space, comparable to double passenger seating. I guess I'm ok with that also.
What I can't find is an answer to how many passengers you can stuff in cargo space? Nothing I can find in the design steps. Page 70 under Off-Road Truck has a note about being able to shove 7 passengers in the 1.5 ton bed. This leads to .214285 tons taken up by a passenger in a cargo area. Don't think that was the intention. You could also interpret the statement for the pickup meaning 5 passengers in the cargo bed (7 total passengers, but 2 are in the cab as listed). That leads to a conversion of .3 passengers per ton of cargo. A little simpler conversion, but I still don't think that was the intention. I can't find any more examples of how many passengers can fit in a vehicle's cargo space, only the one to go on.
The most cramped seats as written is 3 passengers per space. If 1 Space = .25 tons cargo, then that could mean 3 passengers can be thrown into a .25 ton cargo space. In the Off-Road Truck example that would mean 18 (!!) for the 1.5 ton cargo bed. If 1 Space = .5 tons cargo, then you have 3 passengers per .5 tons, or 9 which is more reasonable.
A problem here. Shipping Size is very clear and stated for each vehicle. .5 tons per Space. The Air/Raft has a 4 ton shipping size (8 Spaces), something familiar to most of us. Where I get confused is in the vehicle bays on page 43. These talk of large bays capable of maintenance and small bays which require a crane to pull the vehicle out before, "use or maintenance". 10x shipping size for Spaces for the larger, 5x for the smaller non-use bay. This leads to the following for an Air/Raft:
Shipping Size: 4 tons (8 Space vehicle)
Maintenance Bay for Air/Raft: 40 Spaces on a larger vehicle!
Cramped Bay for Air/Raft: 20 Spaces (and you need to drag it out before even being able to use it)
So the Air/Raft can be placed in my Scout ship taking up 4 displacement tons. Agrees wtih canon and the descriptions in other MgTrav products. But, if I design another vehicle (not starship) I need to allocate 40 Spaces (20 spacecraft tons) to be able to work on it or fly it out. Even if I rule a grav craft in a cramped bay can be flown out, I still must allocate 20 Spaces (10 spacecraft tons). It's not syncing very well (I won't get into HG's bays that would further the confusion).
Should a cramped vehicle bay be one that allows no maintenance, but you can "drive" the vehicle out of it be 2x instead? The maintenance bay could then be 5x. This melds better. My 4 ton Air/Raft parking-only bay needs 8 Spaces (converts directly with spacecraft tonnage), a maintenance bay needs 20 spaces (10 tons in a spacecraft). I could even live with the maintenance bay being 10x shipping size as written (this would be equal to 5x shipping size in tons for spacecraft design), but then you really need to toss the 5x shipping space bay in vehicle design and just have the other option be the straiight shipping size bay (1x shipping size in spacecraft design).
Am I missing something?
I don't have my copy of HG in front of me. I recall it having some issues discussed here long ago when it came to vehicle bays. I think it had similar mentions of different types of vehicle bays. It would be nice if the two design systems synced. As in my vehicle maintenance bay for my 4 ton Air/Raft takes up spaces in vehicle design that equal the tonnage (1/2 spaces) of the same type of bay in High Guard.
Sorry if this was confusing.
