Senshu Maru is a outstanding conversion vessel based on a late model (1997) Japanese research vessel built to military standards and class. She was converted in 2012 with metal work being done in Japan and interior finishing done in the Philippines.

She has a modern white interior style with all guest cabins located on the main deck master stateroom separate on the pilothouse deck. The main deck also has a comfortable lounging area with large TV and a separate dining area for 10. There is also a small breakfast table for two or gaming table aft near the wet bar.
One of several outstanding features of Senshu Maru is her huge outdoor covered living area, with large dining table, wet bar day bed and loung seating. This area could be easily be fully enclosed and heated or cooled. It could also be used as a covered storage and service area for submarines and still be used as a lounge.
Above the the lounge area is a very large boat deck which was designed to also be be used as a helicopter pad but minor modifications would need to be done to bring it into service.  
Senshu Maru's engine room is everything a Explorer Yacht engine room should be, excellent equipment with full back ups a low RPM low hour main engine with veritable propeller, 3 generators on 65KW installed in 2012. She is ready to go around the world with a nod from her new owner.
