Best Boat Stopping System

True Physical Security Protection

Harbor Offshore Barriers™ supported the US Navy to develop, test and deploy its original Port Security Barrier, the PSB. We were the first company to be licensed by the US Navy to produce their waterside perimeter barrier system for commercial applications.

We are continually improving our patented Fixed Security Barrier (FSB™) system (Patent #7,744,313 B2), a stationary barrier with pilings reaching depths of up to 80 ft (25.39 m) and our Port Security Barrier (PSB) models to provide the best anti-terrorism boat stopping system available to government and private sector customers.

  • PSB 600™ – our proprietary model that sets the global standard for continuous net capture systems on pontoon structures.
  • PSB 5500™ – our “heavy-duty” version of the PSB 600.
  • PSB-T – current US Navy standard system first licensed to us in 2004
