LBB2 TLA J2 400/800t Merchant Tug Bosun Class

[Maccat]

OK not quite sure if this is 'canon', is a LBB2 design J2 merchant. Only way to get it to be profitable/viable was to have it be 400t custom streamlined hull, and then have 2x100t standard streamlined "cargo hulls" (6MCr). Also needs unrefined fuel, has HG purifier though.

REVISED: Original didn't have full costs (grr)

Notes:
Ship is rated at Jump 2, 400t. Jump performance limited by Computer model, exceeds 0.1MJn+10Pn fuel by 20t. 600t (tugging 200t) does not meet 0.1MJn+10Pn requirement (has J2, 2wks fuel @600t J2 P2 rating). 2t Avionics reserved for computer upgrades. 2t drive waste space reserved to allow use of 400t M2D, 600t M1D, 800t M1D Maneuver Drive, which would allow a tug of 400t @ J1M1P1 requiring 90t fuel. If 2t avionics, 4t reserved/waste allows E Drive for 100t (600t tow) operation! Includes 8t .036MCr HG 200t TLA fuel purification plant, or interpret as frontier-scout-naval-unrefined rated drives.
Alternate Design remove 2t avionics, 2t drive reserve (waste), add 10t fuel (140t) for 0.1Mjn+10Pn @ J2P2 600t, 4 additional staterooms (16) for 5 High 5 Mid psgr, 100t internal cargo.

Design goal a LBB2 J2 trader able to make standard bank financing, so is a compromise. Uses 400t powered Tug, 2x100t standard streamlined 100t hulls as cargo carriers. Bosun in Italian is Nostromo, though this hasn’t 3 engineers.
[/Code]

OK so this is a LBB2 J2 trader profitable using standard rates, assuming full load. Would work well between pop 6/8 worlds 2 jumps apart, no?

So I guess the question is, is using multiple hulls allowed in LBB2? The hulls towed are just cargo shells (um, demountable cargo pods? could use like cutter 30t open modules but price too high then) They'd need to be in orbit as I don't imagine this launching/deorbiting with stuff attached (Revised, hulls are streamlined so can land?). S07 Traders and Gunboats has the Jump Shuttle for the SB Guardian SDB. This one isn't Nostromo as lacks need for Chief Engineer, but *is* a profitable-on-mortgage LBB2 J2 trader (unrefined fuel granted, but has purifier).

Comments MOST welcome: Enjoy!

There are one or two designs for tugs in Supp 9, and one for a SDB Mover in Supp 7 (IIRC). It's doable. I've never deconstructed to figure out how.

As a GM, if using Bk2, I'd require different jump programs for different configurations.

 

[Mithras]

Just a thought, how about using streamlined cargo pods. These could be launched into orbit using mass driver catapults which the Bosun collects and ships to other stars. There it can offload them at the high port, or send them into the atmosphere to softland with parachutes or glide down to a runway. Perfect for frontier replenishiment.

You're looking at half-mile catapaults, and 25+ G's, for a size 8 world. On a size 6, about 20G's... That stuff better not be fragile!

 

[Mithras]

Gaaaah, GDW used them alot in 2300AD, which is why I suggested them. OK. Use it for metals, grains etc. Not computers or cattle.

Hey it could have been worse, I could have suggested firing them from a giant cannon a la Jules Verne! Calculate the G force on that!!!!

 

[Mithras]

But, otherwise, I must say that the Nostromo was the first ship I ever designed with Bk2, over and over in various ways. I like this version, however.

I'd love to see deckplans!

Well, at least not cattle that can still moo.

 

[far-trader]

Just another quick glance again (sorry) and wondering if it would still be viable (just pondering) if you changed the 4x100ton cargo containers to 10x30ton cargo containers plus 2x50ton modular cutters? Seems like a nice optional version. Almost the same cargo capacity but with integral surface pickup/delivery carried aboard. And more fun (i.e. trouble, adventure, mischief, etc. ) for the players to get involved in.

 

[ThunderChilde]

I hesitate to point out that this would be easier to do in MGT, using TMB and a few goodies from MGT> HG. Docking clamps, perhaps a grapple arm should cover the idea as presented.

 

[Maccat]

Yes, definitely would work with 30t open cutter modules (14x) but then too pricey to make the mortgage and expenses, this was limited by trying to make a J2 LBB2 trader that can meet expenses. Agreed on the other design systems, looking over this idea for a MGT version, though i think i've seen something down those lines already out there.

One of those Engineers is by default the Chief Engineer and gets Cr4400 per month per Book 2.

Or you could cut costs and expenses by using the double duty rules (slash 3 staterooms in the bargain to save more money on fixtures and life support, and add another 12tons for revenue).

Salaries alone:

Pilot-2/Navigator-2 @ Cr9075 per month (Cr4356 per trip)
Chief Eng-2/Steward-1 @ Cr6075 per month (Cr2916 per trip)
Eng-2/Medic-2 @ Cr4950 per month (Cr2376 per trip)

Total salaries @ Cr20,100 per month (Cr9648 per trip)

Saves you Cr3900 per month (Cr1872 per trip)

The bigger savings are the rest of it. Mostly the LS saving of Cr6,000 per trip and the added revenue of at least Cr12,000 per trip (freight). The reduced ship cost of MCr1.5 is only a Cr3,000 savings per trip.

Total savings: Cr22,872 per trip (if I did the math right, rushing things)
