Marine Computers & Onboard PCs – Supply, Installation & Integration
Modern boats are running more software, data and systems than ever before. At Shotgun Marine Services (SMS) and PMMS, we design and install marine-grade computer systems that actually work on the water — not office PCs shoved under a bunk and hoping for the best.
Marine Computers Done Properly – Not Office Gear on a Boat
Marine computers are used for navigation software, digital switching, monitoring systems, charting, radar overlays, logging and control interfaces. But reliability offshore comes down to proper hardware selection, power management and professional installation.
We’re not just an online store. We’re qualified, experienced marine electricians who assess vibration, moisture, heat, power quality and integration requirements before recommending any onboard computing solution.
Built for How Aussies Boat & Work
We design and install marine computer systems for recreational cruisers, offshore fishing boats, charter vessels, commercial and survey craft across Port Macquarie, the Mid North Coast NSW and throughout New South Wales, with Australia-wide consultations available.
Marine computers can be used for advanced navigation software, multi-screen helm layouts, monitoring engines and systems, recording sonar data, running autopilot and radar overlays, or managing vessel systems on larger boats.
Professional Integration Matters
A marine computer doesn’t operate in isolation. We integrate onboard PCs with:
- GPS chartplotters and navigation software
- Radar and AIS overlays
- Autopilot and heading sensors
- Digital switching and monitoring systems
- NMEA 2000 and Ethernet networks
Everything is installed, powered and protected correctly to ensure stability, fast boot times and reliable operation in harsh marine conditions.
Commercial-Grade Solutions Where Reliability Counts
For commercial, charter and working vessels, we design computing systems focused on uptime, redundancy and simplicity. That includes clean power supply, surge protection, secure mounting and long-term serviceability — not over-complicated setups that fail when you need them most.
“Shotgun Marine set up a proper onboard PC for navigation and system monitoring on our boat. Clean install, solid power management and it’s been faultless since — exactly what we needed.”

Marine Computer FAQs
Why use a marine computer instead of just a chartplotter?
Marine computers allow advanced software, multi-screen setups and deeper system integration that isn’t possible on standard chartplotters alone.
Can a marine computer integrate with my existing electronics?
Yes. We integrate onboard PCs with navigation systems, radar, AIS, autopilots and NMEA networks where appropriate.
Do marine computers need special power setup?
Absolutely. Clean, protected power is critical. We design proper power supply, isolation and protection to avoid crashes and data loss.
Are marine computers suitable for commercial vessels?
Yes — when specified and installed correctly. We regularly install reliable onboard computing systems for charter and working boats.
Do you support and service installed systems?
Yes. We provide diagnostics, upgrades and ongoing support as part of the system lifecycle.
