Thanks for the interest and comments chaps. Hancock is still coming along - many hours but little to show for it at present. However, it's beginning to come together now and some features have been removed whilst other details added.
Removed/removing - flag, smoke, rotating radar, all guns except 4x 5", underwater details, many collision boxes, damage models, simplified shadows.
Added/adding - enhanced mast, enhanced radars, improved island details, elevator structures, safety netting, water ejections, cranes, opened doors, whip antennae, improved sponson textures, minor paraffinalia, anchors.
Considering - hanger cut-outs, stack chamfer, steam on a catapult.
Decided not to include - rotating radar, moving elevators, deck lighting.
Another couple of weeks to complete, I guess.
EDIT 9jul13: omissions added
