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.


Route optimization and increased situational awareness

Under Keel Clearance Management

Allows multiple vessels to request and receive port specific S-129 exchange sets specifically analyzed with UKC as a primary focus

Efficient Web Interface

Provides a web based User Interface and a defined Web Data Service for client interfacing

Chart Rendering

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)

Vessel Traffic Management

An e-Navigation application that uses both current and new S-100 based navigation and weather information to analyze, distribute, and manage vessel transits


Port Voyager can be used in both civil and military maritime domains
