Based  on  the  proven efficiency  of  ultra  narrow hulls, this   vessel  is  a  quick, efficient  and comfortable submarine operations platform. Utilizing a modular configuration, this vessel can be tailored to meet  the  specific requirements of the client whilst still  retaining the  same outer  hull forms, primary propulsion system  and structural design.

Primarily targeted at  facilitating  inshore or  near  shore  submarine operations, this  vessel  will provide a level of  speed and  comfort impossible with a conventional monohull design. The low volume hulls  coupled with  the wave piercing centre  module provide both  a safe and comfortable ride  at speed in all but  the worst  sea states.

The  lower  hulls  accommodate all  the  machinery, isolating the  accommodation area  from  any noise  and  vibration. All  tankage is  also  located in  these  hulls   allowing  generous volumes if required. Another unique feature of this vessel is the extensive ballast tanks  situated in the outer hulls  which, when  flooded, allow  the  vessel  to  sink  down  to  the  center  hull. This  provides an extremely stable  platform as well as offering various options for  submarine launch and recovery.
