Swordarm?

[Tshark]

Hi gang,

I just got done with a re-read of "Thunder Below!" and found several references to a "swordarm" not being rigged in. What is a swordarm? I tried several internet searches and came up with nothing.

Thanks!

2A2. Rodmeter. The rodmeter, commonly called the sword, is located in the forward torpedo room below the light draft water line. It projects through the hull of the ship, into the water, and is the unit in which static and dynamic pressures are produced and transmitted to the other units of the system. When in use, the rodmeter extends into the water for a distance of about 3 feet. Being located in the forward part of the ship, the rodmeter contacts water that is least affected by the movement of the ship or by the turbulence of the water created by the action of the propellers. http://maritime.org/doc/fleetsub/log/chap2.htm (http://maritime.org/doc/fleetsub/log/chap2.htm) http://maritime.org/doc/fleetsub/log/img/fig2-02.jpghttp://www.maritime.org/doc/fleetsub/log/chap18.htm (http://www.maritime.org/doc/fleetsub/log/chap18.htm)
