Unmanned vessel

Abstract

Unmanned marine vessels are disclosed featuring various structural properties. A raised deck leveling with the upper side of the vessel allows for larger compartments below deck and implicates special hatching considerations. A upper appliance support frame is provided for positioning external appliances on board the vessel. Air sucked in by the engine may be used to cool compartments of the vessel. Tie points of the vessel may be position on the deck.

1 . An unmanned boat comprising:
 a raised deck;   at least one compartment below said deck having at least one hatch at said deck, and wherein said hatch is capable of forming a watertight closure of said compartment;   an engine in a compartment under said deck wherein said engine is ventilated through said hatch in said deck.   
   
   
       2 . An unmanned boat as in  claim 1  further comprising an appliance support frame. 
   
   
       3 . An unmanned boat as in  claim 2  and wherein a void of said appliance support frame forms an opening connecting the outside with at least one compartment under said deck. 
   
   
       4 . An unmanned boat as in  claim 2  wherein payload is affixed on said appliance support frame. 
   
   
       5 . An unmanned boat as in  claim 1  wherein two hatches both form a water tight closure with at least one compartment below said deck. 
   
   
       6 . An unmanned boat as in  claim 3  wherein an engine of said boat consumes air and wherein some of said air taken in through the void of said appliance support frame, and wherein said air is used to cool said engine. 
   
   
       7 . An unmanned boat as in  claim 6  wherein an engine of said boat consumes air taken in through the void of said appliance support frame, and wherein said air is used to cool said engine and the batteries of said boat. 
   
   
       8 . An unmanned boat as in  claim 1  carrying military oriented payload. 
   
   
       9 . An unmanned boat as in  claim 1  carrying general purpose payload. 
   
   
       10 . An unmanned boat as in  claim 1  having at least one compartment for sustaining crew members. 
   
   
       11 . An unmanned boat as in  claim 1  wherein said boat is adapted for being hoisted at one tie point.
