The Port Voyager software is a maritime port traffic management support system. Its primary purpose is to develop and distribute S-129 Under Keel Clearance (UKC) exchange sets to transiting vessels to reduce the risk of grounding and optimize route plans based on port traffic. The software uses S-100 hydrographic information such as weather, tides, currents, vessel characteristics, and real-time data.


  • An e-Navigation application that uses both current and new S-100 based navigation and weather information to analyze, distribute, and manage vessel transits
  • Allows multiple vessels to request and receive port specific S-129 exchange sets specifically analyzed with UKC as a primary focus
  • Provides a web based User Interface and a defined Web Data Service for client interfacing
  • Can be used with FairSeas Unify to provide a data source to both new and legacy systems, generating S-129 compliant product overlays that can be distributed and used within geospatial applications such as Portable Pilot Units (PPUs) and Electronic Chart Display and Information System (ECDIS)
