DOWNLOAD research document on what boats had what type of shutter (also available in
LIBRARY)

Anything “Gato” (/Balao) means wild variation, numerous inconsistent exceptions, and individuality.
The Torpedo Shutters are no different! RESEARCH your specific boat and time period to find out what shutters it (most likely/probably/possibly?) had.
In general, the Shutter story goes something like this...
“VALLEY”
A long, scoop-like concave shutter, from bow piece through entire shutter door. A holdover from Tambor, seen mainly on
early Electric Boat (EB) boats: SS212-214, SS215-221, and early Manitowac boats. Portsmouth-built Tambors/early Gatos had
the flat-angled style shutters (termed “Balao” here).
“SPOON”
A flat shutter body, but a spoon scoop at the hinge end, meeting a spoon scoop at the bow. The main flat was
reinforced with a strengthener. The Revell Gato kit depicts these, though in a mishapen and totally inaccurate way. The kit is also modeled after the USS Cobia,
which presently has Balao style shutters! (These may have been added later, the launching photos of Cobia are inconclusive). The spoons seem to be
the rare type of shutter, limited to Mare Island boats and a few odd others.
“BALAO”
A flat shutter body with a flat, angled piece where the spoon used to be, meeting a flat-angle at the bow.
Obviously easier to build, and probably quicker. A shutter like this was used in non-EB early Gatos and even some Tambors. Late Gatos and the Balaos had these shutters.
Photos and plans show a much more complex shape then a “flat” body, the main feature being a very slight square and concave channel in place of the
strengthener. But some illustrations and even a few photos show a convex stengthener, much like the mid range shutters, but very wide.

The Revell 1:72 Gato kit is generally accurate, but can be improved, especially the shutters. The kit depicts a wildly inaccurate version of a type of shutter
only used on a small number of boats.
