(a) a plurality of barrier float assemblies connected to one another to form a chain of connected barrier float assemblies to protect said port facility;

(b) each of said barrier float assemblies including:

(i) a longitudinal net support beam;

(ii) a generally rectangular shaped synthetic fiber capture net extending vertically upward from said longitudinal net support beam, said synthetic fiber capture net having a standard length which is approximately the length of said longitudinal net support beam, and a height which is sufficient to prevent said waterborne craft from penetrating said port facility wherein said synthetic fiber capture net has a plurality of equally spaced apart horizontal members and a plurality of equally spaced vertical members;

(iii) a netting support structure extending vertically upward from said longitudinal net support beam, said netting support structure including a pair of fence post affixed to said longitudinal net support beam wherein said pair of fence post are positioned inward a preselected distance from each end of said longitudinal net support beam and have said synthetic fiber capture net attached thereto; and

(iv) a pair of pontoons attached to said longitudinal net support beam and orientated perpendicular to said longitudinal net support beam, said pair of pontoons for each of said barrier float assemblies keeping said port security barrier afloat in a marine environment; and

(c) a plurality of flange sleeve connectors, wherein one of said plurality of flange sleeve connectors is attached to each end of the longitudinal net support beams for adjacent barrier float assemblies to connect said adjacent float barriers assemblies to each other;

(d) a netting termination post extending vertically upward from the longitudinal net support beam for said barrier float assemblies positioned at each end of said chain of connected barrier float assemblies, said netting termination post being secured to an end portion of the synthetic fiber capture net of said barrier float assemblies positioned at each end of said chain of connected barrier float assemblies; and

(e) a latching connector assembly located at one end of the longitudinal net support beam of said barrier float assembly positioned at each end of said chain of connected barrier float assemblies, wherein said latching connecter assembly is adapted for coupling to and uncoupling from a latching connector receiver mounted on a mooring buoy allowing for said barrier float assembly positioned at one end of said chain of connected barrier float assemblies to be connected to said mooring buoy and disconnected from said mooring buoy, wherein said latching connector assembly for each of said barrier float assemblies located at each end of said chain of connected barrier float assemblies comprises:

(i) a latching connector spear having one end attached to the longitudinal net support beam for each of said barrier float assemblies located at each end of said chain of connected barrier float assemblies, said latching connector spear having an angled surface which is angled inward at the other end;

(ii) a tension element centrally located within the interior of said latching connector spear and a pin to secure one end of said tension element in a fixed position within said latching connector spear, wherein said tension element extends outward from said latching connector spear; and

(iii) a lanyard having one end connected to said tension element and an opposite end connected to a towing device, said lanyard passing through the interior of said latching connector receiver to said towing device, said towing device when connected to said device pulling said tension element and said latching connector spear into the interior of said latching connector receiver, wherein said latching connector receiver has an alignment member which has an inner surface angled to receive the angled surface of said latching connector spear and a locking element which engages said tension element preventing rearward movement of said tension element from said latching connector assembly.
