In recent years, there has been a steady increase in installed propulsion power for commercial ships. Salient results of the 1997 workshop on High-Speed Sealift, Ritter and Templeman (1998), indicate that surface effect ships (SES) are the least-power options for speeds greater than approximately 45 knots with both near-term and far-term propulsion technology. The availability of marinized gas turbines in the 50 MW range and the commercial development of large waterjet units that can be matched to these gas turbines have led to a re-examination of the potential of SES for fast sealift applications. The results of the workshop indicate that advances in lightweight structural design and improved efficiency of prime movers and propulsors are key to achieving ships with speeds in the 60 to 80-knot range. A physics-based design synthesis model has been employed to evaluate the feasibility of ver high-speed, long-range cargo transport using surface effect ships. The results of the investigation indicate that the SES is a viable option for high-speed cargo transport and within the reach of today' technology. Near-term technology projections for structure and machinery, as well as potential advancements in the state-of-the-art of air cushion technology will improve this option further. Advances in materials arid design for cushion end seals, previously a source for concern for adequate SES reliability, have now progressed to make this issue of less concern.
