  • Standard Horizon GX6000 ($400-600) offers integrated AIS receiver, dual-channel monitoring, and fog horn capabilities. Installation requires professional mounting, proper antenna placement, and MMSI registration
  • Annual maintenance includes antenna inspection, power output verification, and DSC testing costing approximately $150-200. Professional calibration may be required every 2-3 years
• Handheld VHF Units:
  • ICOM IC-M94D ($300-400) features built-in GPS, float-and-flash technology, and 6W transmission power. The unit provides up to 10 hours of continuous operation and includes emergency strobe light
  • Standard Horizon HX890 ($250-350) includes DSC functionality, GPS, and compass. Waterproof construction allows submersion up to 1.5 meters for 30 minutes
  • Battery replacement every 2-3 years costs approximately $50-70, with annual testing required for emergency functions.

2. Satellite Communication Systems

• Inmarsat Systems:
  • Fleet One Coastal ($3,000-4,000) provides voice and data services up to 100nm offshore. Installation includes stabilized antenna and below-deck unit
  • Fleet Broadband FB150 ($5,000-7,000) offers global coverage with voice and data capabilities. Professional installation adds $1,500-2,000 to system cost
  • Annual service plans range from $600-2,400 depending on data allowance and voice minutes
• Iridium Systems:
  • Iridium GO! ($1,000-1,200) provides global voice and basic data services through smartphone integration
  • Iridium Pilot ($4,000-6,000) offers broadband data and multiple voice lines for commercial applications
  • Installation costs range from $800-1,500 depending on vessel configuration
  • Annual airtime plans start at $500 for basic service up to $5,000 for unlimited data

3. Emergency Signaling Devices

• Visual Distress Signals:
  • SOLAS approved flare kits ($200-300) include parachute flares, hand flares, and smoke signals
  • LED emergency flares ($300-400) provide extended operation without expiration concerns
  • Annual inspection required with replacement of expired pyrotechnics
  • Storage requirements include waterproof containers in accessible locations
• Sound Signaling:
  • Electric horns ($100-150) with automatic fog signals and manual operation
  • Compressed air horns ($200-300) for backup emergency signaling
