Myrtran I did a proportional comparison basing the shuttles on a 24' design (each shuttle is 32 pixels) and I got a length of 1,644.75 feet or 501.3213m Admittedly the decks are a little bit excessively large 13.5 feet without even factoring the spacing between the decks. I think the minimum size to shoehorn the shuttles in this drawing would be 1,315.8 feet or 401.057 meters (tight fit); based on deck-space it would appear that 1370.625 feet or 417.7678 meters would accommodate 10' decks with 1.25 feet of spacing or 7.5 inches between each deck (the decks looked to be around 10' high); with provision for provision for 12' decks not counting space in between you'd be right set at 1644.75 feet. Regardless, I don't think most decks are going to be 12-feet high (you'll see an occasional deck that has a larger ceiling than others), so the 417.77 meter frame would probably be fine based on these measurements. When I looked at that drawing, I got 1644.75 feet (I proportionally measured the pixels for the shuttle craft at 24 feet), provided I assumed a 22-foot shuttle (or a slightly "tighter" fit), I'd get 1,507.5445 feet. I'm not sure where you got 1,420 or 1,437 from. Maurice May I remind you of the scene in Star Trek V when the Enterprise-A went off to warp after Kirk crash-landed? The ship traveled sideways relative to the warp-streak! Regardless, based on what I said with the minimum size for the shuttles, 1315.8 feet would do the trick so I'm fine with 1,420 or 1,437 if it all fits; with that said, the refit enterprise to the same scale ((1000/947)x1437) would be 1,517.423 feet or 462.5121 meters!
