Well, there's the answer for the US Navy's hunter killers then, just give your dad a call:rotfl:
Update: Further investigation reveals that the sail problems are manifest. The front faired-in angle is too steep on the sail in the kit, and the rear slope of the sail sweeps down incorrectly, starting in the wrong place and being too severe rather than emulating the graceful curve of the real thing. This can be seen on the composite comparison shot below; even though the shot angles differ, the error is still apparent, as is the wildly inaccurate and oversized door placement for the masts and the incorrect placement of the cockpit:
So, it was out with the scalpel and needle files to remove it all! Thus, filling it all in and re-drilling the location holes for the masts is on the cards, as is constructing the cockpit more accurately with the correct windscreens, but before that, I'll have to reprofile the sail, which should be possible with filler and some more comparisons with photographs and schematic drawings. Picture of the crappy detail having been removed:
