Here is what the Orca could be in Traveller Tech.
The tonnage is loosely based on approximation from other ship deckplans and some square patterns layering in PaintShop Pro to do at-a-glance calculations.
NB: This is my first try at Ship Desing, done with Mr. Falkayn's nice Spreadsheet, imported in OpenOffice which works nice

(1) well... kinda

(2) look at those BIG **** Thrusters in the Zaon Design
(3) In those Handy Tanks on Deck 2 and 3
(Orca pictures shows a double barreled thing at
the center and two other "guns" on each side in
the back, plus two "guns" in the front on the
engines)
(5) (Had only 4 stateroom on the plans so I put
them in double to get enough engineer. There
is one bunk left for another crewmember if
necessary)
(6) There aren't any in the stateroom. Consider
them ripped off to get another bed in for the
second crewmember
(7) Two in the nose (port & starboard)
(8) As seen in the Orca's Picture</pre>[/QUOTE]I'll now explain some of my desing decision.
I based my size guestimation by compairing the couch/bed size and setting a grid pattern over the screen dump of the Orca in Paint Shop Pro. I then proceeded to simply count the square of half the ship (2 square = 1t so counting half the ship = ship tonnage) and then rounding off a bit to get a nice number instead of 818 Tons.. My guestimate could easily be off by 25 Tons, but what the heck
4G Thrusters: Can't really get around that, just look at the SIZE they've made them. My idea is to make the Orca a special "High Grav" trader, where normal 1-2G carft wouldn't even lift off the ground.
Jump-2 + J2 Fuel: Deck 1 is almost all machinery and the like. Since J2 and it's fuel takes more space, I've decided to explain Deck 1's machinery as the Jump Fuel tanks and the high debit pumps to drain/balance the fuel.
Streamlined Dock. This could be quite nice for a Pinnacle, and would fit the picture. Just thought I missed some detail for Jump tho. maybe you couldn't use the Pinnacle when jumping.
Hope you like it
PS: Feel free to modify it as you like
