Maritime Operations

Scroll to explore

Harbors run on VHF. Towerless keeps the timeline.

Harbor calls and berth requests go unrecorded. Towerless logs Marine VHF to document vessel movements.

Public marine radio activity in range.

Captured and indexed.

Marine Traffic (AIS)

AIS vessel identity, position, speed, and heading correlated with radio activity where available.

VHF Channel Monitoring

Configured Channel 16, Channel 13, and port working channels captured and transcribed for review.

Drone Tracking (Remote ID)

Remote ID drone broadcasts captured when available near harbor and port zones.

NOAA Weather Broadcasts

Weather broadcasts can be added to the harbor timeline where configured.

DSC Monitoring

DSC broadcasts can be captured where available and configured for review.

AI Transcription & Logs

Searchable marine radio transcripts connected to vessel context where available for incident review exports.

Why operators choose Towerless.

No new radios. No workflow change. The local record begins when power is connected.

No transmit.
No interference.

Towerless listens only. It does not transmit, control, or interfere with existing operations.

Works without
internet.

The record builds locally. Cloud sync and dashboards are strictly optional.

Reports when
you need them.

Export timelines for safety review, insurance support, management review, and operational reporting.

Built for the site
you have.

Indoor, outdoor, self-install,
assisted deployment, or secure
government workflow.

The Situation:

When a marine incident occurs, operators need a clear sequence of vessel calls, movement, and coordination.

Towerless passively captures configured Marine VHF activity and builds a searchable harbor timeline with vessel context where supported.

Harbor calls should not disappear.
No radio replaced.
No harbor disrupted.

Ports, harbors, marinas, bridge operators, and waterfront facilities depend on VHF radio every day. Vessel movements, berth instructions, passing arrangements, and emergency calls all happen over the air.

But most harbor communications vanish the moment they end.

Towerless records configured marine radio activity and connects it to a searchable operational timeline. Where AIS data is available, vessel context can be linked for review.

It sits beside existing systems without transmitting, interfering, or changing port procedures.

THE SYSTEM

Built to sit beside the operation.

  • Listen only.
  • Process locally.
  • Link context where supported.
  • Export the record.
  • No workflow change.

Designed to build a local supplementary record without transmitting, interfering, or changing the workflow.

System Capabilities

Mission Areas

Towerless can be installed alongside port, marina, or waterfront infrastructure.
No new VHF equipment. No operational disruption. No change to vessel traffic procedures.
A searchable supplementary record of vessel coordination when the timeline matters.

Four layers. One dashboard.

Voice transcription, identity correlation, position logging, and operational context — searchable locally and exportable when needed.

Authority Vehicle
The Authority

Marine incident reviews often depend on the record available after the fact. When vessel movements, passing arrangements, or harbor calls are disputed, Towerless gives operators a searchable timeline of configured Marine VHF activity and vessel context where available.
