Nevada had the usual double raft (25 inside 40) arrangement on the sides of turrets # 2,3, 4 but not on turret #1
Turret #2 also had two 40 man rafts on her top on the starboard side of the top.
Turret #4 had four rafts on the top. All were painted white.
In this view you can see the crew has taken two of those rafts off the top. You can see the crew trying to get one of them into the water.
This next image show the double rafts on turret #3 side. It also shows at least 3 hidden rafts up against the vegetable storage area just under the main mast.
I'll try to do another Battleship for you soon.
