An improved runner for use with a SAILRAIL hydrostatic bearing levitation system is disclosed. The runner uses a substantially solid core having a degree of flexibility in a vertical plane, a thin pad of flexible, compliant material extending transversely around the core, and an outer flexible, compliant sheath enclosing the pad and the core. Flexibility is enhanced by a longitudinally extending slot cut into the core from the upper surface thereof. The side walls of the core are flat and straight and meet the lower convex surface of the core at a generally sharp longitudinal edge. Also the ends of the runner can angle upwardly to enhance the ability of the runner to traverse joints, gaps, or imperfections in the SAILRAIL rail. The runner can be secured to a deck member and provides specific advantages over prior art runners which had a larger profile, were more expensive and were not as efficient as the low profile runner of this invention.
