MARINE PUSH-TOWING TRANSPORTATION SYSTEM Abstract of the Disclosure The present invention relates to a marine push-towing transportation system. The system is comprised of a first vessel having a notch at one end with the notch having a pair of oppositely disposed wings. A second vessel is provided having a bow portion and sides. A coupling unit is provided for coupling the vessels when the second vessel is received in the notch between the wings. The coupling unit includes at least three first coupling assemblies secured to one of the vessels. Each of the first coupling assemblies includes at least one bearing member having opposed, substantially vertical bearing surfaces with one assembly being disposed for engagement generally forward of the notch and the other two being disposed for engagement generally rearward and on opposite sides of the notch. At least three second coupling assemblies are secured to the other vessel, each being disposed so as to be engageable with the first coupling assemblies. Each of the second coupling assemblies includes a gripping unit for frictionally engaging the bearing surfaces. Each gripping unit is comprised of first and second gripping members, the first having a surface engageable with one of the bearing surfaces and the second having a surface engageable with the other of the bearing surfaces. The first gripping member is mounted for movement in a direction generally transverse to the bearing surfaces. A unit is provided for effecting engagement of the gripping units with the bearing surfaces.
