An articulated crane with 13' hor- 

 izontal reach, with a lift capability of 

 2 tons, is currently installed on fore- 

 castle port side ; a second and similar 

 crane is contemplated for future in- 

 stallation. Since no lift capability is 

 currently existent on the after deck, 

 futui-e i)lanning contemjilates the pro- 

 curement of a crawler crane with a 

 5-ton lift capability when funds be- 

 come available. 



The vessel deactivated July 1, 1970.
