An inflatable drop stitch panel and method of use is provided with a plurality of rigid embedded fasteners inserted in apertures in the panel. In the method of use for the inflatable panel, the uninflated panel with embedded fasteners is placed on the deck of a surface ship and secured to deck fittings by tensioned lines. The panel is then inflated to operational pressure and equipment is secured to the panel using the embedded fasteners. The inflatable panel is a temporary structure and requires no permanent changes to the deck surface, such as drilling holes and welding fasteners.

An inflatable deployable mast fairing assembly is provided with a rigid foundation, a hydrodynamic fairing and at least one soft actuator. The hydrodynamic fairing is shaped to close an aperture formed between a deployable hardware system and a sail bay opening. A first soft actuator connects to the rigid foundation at one end and to the hydrodynamic fairing at another. Fluid pressurization elongates a first soft actuator coaxial to the deployable hardware system to fittedly position the fairing in the aperture with a void in the fairing to receive the hardware system. If the rigid foundation is sail-mounted, a second soft actuator connects to the sail-mounted foundation opposite the first soft actuator and to a counter flange mechanically connected to the hydrodynamic fairing. A second pressurization elongates the second soft actuator coaxial to the deployable hardware system to retract the hydrodynamic fairing from the aperture.

A sensor platform is provided with a rigid hull having a planar shape having a bow, stern, a port and a starboard side. The platform includes an inflatable perimeter tube having sides extending along a perimeter of the hull. A tow connection is at the bow and rigid control surfaces are at the stern. A planar sensor array is disposed within the platform. The planar sensor array includes inflatable sensor panels attached to the port and a starboard side of the perimeter tube. Each of the inflatable sensor panels has a plurality of sensors embedded with electrical conductors for power and data transfer. A manifold disposed within the platform operationally connects to the inflatable perimeter tube and the inflatable sensor panels. An electrical controller disposed within the platform connects to the sensors and the manifold.
