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.
