VI. Submarine Construction

Submarine construction/operation is subject to the same rules as for surface vessels except for the following:

A. Design

1. All subs that can submerge may be Dynamic Diving or Active Ballast type.

 

2. Active ballast submarines will utilize a free flooding ballast tank to cause the vessel to submerge. Purging the ballast tank may be accomplished by pressurizing with air, Propel or CO2 or by mechanical means (e.g., piston method, bellows, etc.). Any method that evacuates water from the ballast tank MUST NOT evacute water from the rest of the inside of the sub.

 

3. Submarine decks must be penetrable per Figure 1.

 

Penetrable Deck Area for Submarines

The Deck must be penetrable except for the following areas: A. The solid bow and stern areas are allowed as per the hull construction rules B. A 1" wide strip running athwartships (one allowed forward of the conning tower and one allowed aft). This is primarily to facilitate deck hatches, if desired. C. From 1" forward to one inch aft of the conning tower. D. Where bulkheads support the deck. The number of bulkheads may not exceed that allowed by the hull construction rules E. 1/2" inch inboard from the deck edge.

Additional Impenetrable Deck Areas: F. 3/16" from equipment penetrations (i.e. deck guns, safety switches, ammo fill ports, etc).

 

4. The sides of the submarine are penetrable as per the surface vessel construction rules

 

5. All functioning torpedo tubes must be located in scale positions.

 

6. Torpedoes must be 1/4" diameter by scale length.

B. Operation

1. Submarines are not required to have the ability to dive/surface.

 

2. A sink is defined as the inability to surface or the deployment of any recovery devices.

 

3. Submarines must sink with internal spaces flooded and ballast tanks dry (if ballast tanks are used).
