Yes, if its already statted for the 200 dtons of volume in ship docking space, you don't ALSO pay for having that volume filled with a 100 dton ship. Empty or full, the engines have to move the volume (not the mass). Its no different than jumping with empty holds. The volume is still part of the jump field. Because Traveller physics
If you are essentially just grappling the ship to your ship, then you would have to treat your ship as the volume of both ships for engine purposes. Arkathan's example of a 200 dton ship would exceed the internal space of a corsair, so it would add to the volume of the corsair because that's not already included.
If it was just increased the jump drive to a jump 3 for instance as the ship currently RAW stands it should be capable of Thrust 3 and Jump 3 on its own, Thrust 2 and Jump 2 while carrying a ship up to at least an extra 100 dtons (plus the 100dtons in the dock) or Thrust 1 and Jump 1 while carrying a ship up to at least an additional 400 dtons (plus the 100dtons in the dock). Unmodified it could carry a 200dton ship at thrust 2 and Jump 1.
If for instance the J2 drive was removed and a prototype H1 drive was installed then you have plenty of power to jump approximately the same size, (15 dtons < 25 dtons I add batterys for the empty manatory additional 5+dtons) as the J2 to wherever you really wished as long as you have the power points to do it i.e. jump 9 with a 200dton ship j8 with a 400dton ship etc...
These ships are going to be acting like the Vargar "the bloody eye gang" and using Zhodani tactics to irritate the Imperium and Aslan commerce in POD.
But I was using "A Nexus Linkage Device which allows up to nine of one type of components to be used together. It can work on
jump drives,
maneuver drives, and
power plants, but not in combination. For instance, it can not link a
maneuver drive and a
power plant. The device employs an additive effect with distinct limits.
E.g. three J-1
drives (J-1 + J-1 + J-1 = J-3) could be used to give a J-3 capability. A set of standardized fittings, designed alongside the standardized sizes of components. If, for example, two
jump drives of size A are to be used on the ship, the Nexus Linkage Device sits between them and allows both of them to be used at once. This can be because one size (say, size A) is too small for a given ship design but the next size up (size B in this case) is too large, but 2 or 3 of the first size would be just right." idea from T5
In the Nishemani she has a 100dton space for the price of 110dtons used at 400dtons so it should reason that if I double the space to 200dtons internal it would require 220dtons approximately 500 dtons correct, not thousands of dtons to capture a 200dton ship which is the standard size floating around and the jump net would cover the volume part of the jump field. Now there are also 300 and 400 dton civ ships around as well so if I use the Nexus black boxes"described above" one for the jump drive and one for the power plant or just rely on battery's to supply the boost into jump since were on a power point system now.
