Merc Cruiser errata

Got the Patrol Cruiser sorted, in the process figuring out the way I was treating Book 2 custom hulls as HG hulls at the same price point (unstreamlined == cylinder, streamlined == cone) meant the app does not (yet...) recognise Book 2's free fuel scoops.

No doubt someone is going cross-eyed at the cross rules hull matching. In particular that cylinders in HG are partially streamlined. It turns out the unstreamlined Mercenary Cruiser is described in The Traveller Book and Broadsword as capable of GG refueling. Of course this assumes the presence of fuel scoops which the app does not (yet...) recognise. The Mercenary Cruiser is the only Book 2 example of an 'unstreamlined' custom hull ship.

Regards CT Errata, the Mercenary Cruiser matches in price, but only has 60 ton of cargo capacity versus Book 2's 80 ton. So I've attached the output below for review to see if I have lost 20 ton somewhere!

Because the cost calculation is not intuitive (to demonstrate a match with CT Errata), I've attached that as well.

Mercenary Cruiser (type C)
800 ton, TL 12 Civilian Design, 414.90 MCr
42 crew (Command: 1+1, Engineers: 1+3, Marines: 1+34, Medic: 0+1)
no passengers

Cost match with CT Errata

+ 53.640 MCr, cost of 2 Cutters and ATV modules (2 x (28 + 1.8) MCr) after 10% discount
+ 02.700 MCr, open and fuel modules (3 MCr) after 10% discount

429.804 MCr (CT Errata v1.1; includes 10% discount for standard design; includes cost of two Cutters, four modules, two ATVs and an Air/raft)

Longish post, so just to restate - am looking for reasons why this design cannot fit 80 tons of cargo space. Cheers!

according to B2 1977
the Merc Cruiser carries 2 Pinnaces not Cutters

Pinnaces mass 40 Dtons not 50

10 fewer Dtons x2 = the missing 20 Dtons cargo
 
That sounds highly plausable. I'll note that as the reason, especially as it doesn't look like anything else has been spotted.

Cheers!

Also, if there is an "open" module, that can include 20 dtons of cargo space in its design. (Well, it could include 30 dtons, but since we're looking for 20....). Also, too lazy to look it up, do the ATV modules have cargo already in there? 10 dton ATV, in a 30 dton module, carry the one, er....
 
the 1977 edition Merc Cruiser used a standard hull

165 ton drive space
only used 125 tons of drives
40 tons waste space

and it still housed the 2 ATVs - 20 tons

that's the 60 tons for the spare cutter modules of the 1981 edition
 
Ta. Will note that as well. Its bound to come up again.

I'm dabling with Book 2 small craft as well. Out of curiousity, could you list the G ratings of the various small craft in the 1977 edition. The Ships boat and Pinnace for example are in the ball park price wise, if they are both 4G. Kinda makes me wonder if they were massaged in the new edition to increase the differentiation between the small craft.
