If you operate a small fleet — a handful of fishing vessels, workboats, tugs or offshore supply vessels — you have probably noticed that the maritime software market was not built for you. The big Planned Maintenance Systems were designed for ship managers running dozens of vessels, and priced accordingly.
So what are your realistic options for free or low-cost ship maintenance software? This article walks through the landscape honestly — including where free tools genuinely work and where they fall short.
📊Option 1: Spreadsheets and Paper
Most small fleets start here, and for a single vessel it can work — for a while. A well-structured Excel sheet can track service intervals, running hours and spare parts. The problems appear when you scale: no automatic reminders, no audit trail for ISM compliance, no crew access on board, and one corrupted file away from losing everything.
🏢Option 2: Traditional Enterprise PMS
Systems like TM Master V2, AMOS, SERTICA and BASSnet are excellent platforms — we know them well. But based on our market experience they typically run around $1,500 per vessel per month before implementation costs. For a three-vessel fleet that can exceed $50,000 per year, which is rarely defensible for a small operator.
🆓Option 3: Free or Freemium Maritime Software
A small number of platforms offer genuinely free tiers. The important word is genuinely — many 'free' tools in this space are time-limited trials, stripped-down demos, or generic maintenance apps not designed for vessels at all. Before committing, check:
- Is it a real PMS? Job scheduling by running hours and calendar, component hierarchies, counters and class-required jobs — not just a checklist app.
- Does it work on board? Crew must be able to register jobs and read manuals from the vessel, including offline or on poor connectivity.
- What are the limits? Vessel count, user count, data caps — and what happens to your data if you outgrow them.
- Does it support compliance? ISM requires documented, traceable maintenance records.
🚢SeaVesselManager Community Edition: Free for Up to 4 Vessels
This is exactly why we built SeaVesselManager with a Community Edition that is free for fleets of up to 4 vessels — permanently, not as a trial. You get the complete platform: planned maintenance with running-hours scheduling, spare parts inventory, certificates, purchasing, trip planning and a crew portal that works on phones in the engine room.
- All modules included — the free edition is not feature-limited.
- 30-day free trial before activation, license issued after review.
- Self-hosted on your own servers, or Managed Cloud if you prefer we run it.
- Upgrade path when you grow: Professional at $169 and Enterprise at $399 per vessel per month.
What we ask in return: Community Edition includes an attribution requirement — we may use your company name and logo in our marketing, and a "Powered by SeaVesselManager" notice stays in the interface. The attribution disappears the day you upgrade to a paid plan.
📈When Is It Time to Move Beyond Free?
- You add a fifth vessel — then you need a paid plan with any vendor, including us.
- You need guaranteed response times, SLA-backed support or a dedicated contact.
- You want the attribution removed, SSO/AD integration, or custom development.
- Head office needs fleet-wide analytics across more than a handful of vessels.
The good news: upgrading is a license change, not a migration. Your data, users and configuration stay exactly where they are.
📌 Key Takeaways
- ✓Small fleets have three realistic options: spreadsheets, enterprise PMS, or genuinely free maritime software.
- ✓Enterprise systems like TM Master V2 typically cost around $1,500 per vessel per month (indicative) — rarely viable below ~10 vessels.
- ✓Check that 'free' means a real PMS: running-hours scheduling, offline crew access and ISM-ready records.
- ✓SeaVesselManager Community Edition is free for up to 4 vessels with all modules — the trade-off is attribution, not features.
