I can't remember if I posted this or not. I'm sorry if you've already
seen it.

notes:
This is basically a TL14 craft, but I used a TL13 power plant for
maintenance reasons, since it was just as good for the purpose. The TL15
equivalent power plant is 13 m^3, 26t, and MCr2.6 so is definitely
worthwhile, unless used where maintenance of TL15 will be a problem.
The TL15 version of this craft costs approximately the same (if
available), but the power plant, the computers and other electronics are
smaller, so it has an additional 15 m^3 or so of space available for
cargo or other use (fuel purification machinery for example). Also, at
TL15 the control points are sufficient that an electronics crewman is
unnecessary.
This design is intended to be launch-bay interchangeable with the
standard ship's boat. (The standard ship's boat is considerably heavier,
due primarily to its TL12 power plant.)
It's fairly common to run this with two crew. It's also fairly common
for double occupancy staterooms, so up to six (including crew) can travel.
Higher jump capability actually works out to about the same overall
space, due to increased fuel efficency. for a jump/4 version the jump
drive becomes 21 m^3. Reducing the fuel capacity to 150 m^3 still allows
four parsecs of jump plus 24 gturns, plus we've gained 12.6 m^3 of space.
Summary of TL15 version: jump/4, fuel scoops & purification, slight
increase in cargo space, increased flexibility in crewing.

p.s. I'm open to suggestions for good names for this "class" of vessel.
p.p.s. Also, I'd like to know if you see something I've done something
wrong in the design.
