FLOOD VENT
TEMPLATES
The Revell Gato kits lack one of the most
important features for any submarine: The free
flood openings and the flood vents found along
the bottom of the boat. Without these features,
the boat would be little more than a low riding
destroyer. These templates are designed to be
used along the bottom of the hull (the keel)
and are located in the following positions. Please
note that not all sheets will have all of the
numbers indicated, due to the different patterns.

This drawing is of the bottom of the kit and shows the weld
lines on the hull. The numbers indicate which panel of the
template goes into a given area. All of the panels are to be
placed centered on the keel.
