*chuckles at MTB* Good recovery there, mate!
So far in the second half of my modeling career, the three 1/700 ships have each taken longer than the 1/72 bomber I am currently working on, because as others have noted, steel ships at least are really a series of sub-assemblies that are then attached to the hull.
Some of these sub-assemblies are almost models in themselves. I still have vivid memories (well, OK, deep emotional scars) of folding the SPS-49 photoetched radar antenna for my 1/700 Perry class frigate. The suggestions I got on here were about the only thing that enabled me to win that particular battle.
But for me, it is the process, not how long it takes, that is what I derive enjoyment from. That, and spending an evening detailing the cockpit of a B-25B is wayyyyyyyyyyyyy cheaper than a prolonged stay in a padded cell.
