 Subject: [TML] Reflections on LBB2v2 versus HGv2 for drives

 STARTING OBSERVATIONS:*
  "Standard hulls" from LBB2 are not explicitly
 allowed by the HG build sequence.  Although much cheaper
 for smaller craft up to 400-ton, the enforced
 compartmentalisation of "standard hulls"
 drastically limits Jump capacity.  100-ton craft are
 limited to J2.  200-ton to J1.  400-ton to J2.*

I'm a little confused here;
(but then this *is* Traveller, no?)  ;-)

I just looked at my LBB2v2 (from the DeLuxe set) & also the hb 'Traveller Book' & the charts there show (on the 'Drive Potential' table) that J6 can be obtained up to 2000dT, J4 up to 3000dT, J3 up to 4000dT, & J2 up to 5000dT.
5000dT is as far as the table goes for hull size.

In the 'T'Book' there is detailed a 'Type M' (subsidized liner). Using a 600dT hull, it has J3 & 1G.
In addition there is the 'Type C' (mercenary cruiser). Using an 800dT hull, it has J3 & 3G.
Also there is the 'Type T' (patrol cruiser). Using a 400dT hull, it has J3 & 4G, which would seem to contradict the "400-ton to J2" limit you mention above?
