Anti-roll tanks were installed in late 1961 and full scale sea trials were con- 

 ducted by the David Taylor Model Basin in December 1961 [40]. Figure 2 shows 

 a photograph of the ship and indicates the general tank location while Fig. 3 pre- 

 sents a schematic sketch of the tanks. These tanks displace 75 tons when filled 

 with 6.5 feet of water. The trials were conducted over a three-day period and 

 Figs. 4 and 5 show the measured sea spectra.
