OK, this is based on the

math I did here, on what it would realistically take to slowboat cargo between two star systems in Battletech in the event, as in Herb's setting, that JumpShip travel is lost, but DropShips can still be built.

OK, first off, I gave everyone first-class quarters, to ensure they had sufficient room and amenities for a long flight. I doubled up on the number of people listed for the crew, which was 9 officers, 55 enlisted/gunners, and 100 bay personnel, for 164 total. Throwing on 32 marines, that would be 328 + 32 --> 360 personnel, but we're also going to need 12 base personnel, doubled, for the large naval comm-scanner suite I'm adding, so that's 384 total.

Supplies for 384 people, at 60 tons each, works out to 23,040 tons. I've added 0.21 tons to that, put it in its own insulated cargo bay to represent their supplies, which allowed that bay's mass to round up to an even 26483 tons. Next up, I put six laser AMS fore and aft, along with a single SCL/1 to function as a communications laser, along with that naval comm-scanner.

I'm left, then, with 36,681 tons of cargo. The next big question becomes how many tons of spare parts or machinery and feedstock to make spare parts you need. In that thread, I calculated it at 1% of ship's mass per year, which probably isn't realistic, but I don't recall where the actual rules for that are anymore.
