Flood Vent Templates


The Trumpeter 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.


72-701 Gato/Balao Class Flood Templates

This set is designed for the majority of the boats. This pattern was used on the later Gato class and all of the Balao class units. It is designed to be applied between the weld lines present on kit hull and includes the free flood openings, flood vents, fuel tank manhole covers and sonar openings.
