If you're weighing up Offshore SMS for your AMSA or Maritime NZ Safety Management System, here's an honest head-to-head with SMS Builder — what each does best, and where they differ. Updated June 2026.
Offshore SMS is a well-established, Australian-built marine app. It's a genuinely good product — so this isn't a hit piece. The honest answer is that Offshore SMS and SMS Builder are built around two different jobs. If you understand which job you're trying to do, the right choice becomes obvious.
Offshore SMS is, at its heart, a digital logbook and crew app. SMS Builder is the Safety Management System document itself — the thing your surveyor actually reads.
| SMS Builder | Offshore SMS | |
|---|---|---|
| Core job | Writes the SMS document for you | Digital logbooks & crew workflows |
| AMSA (Marine Order 504 / NSCV) | Yes | Yes |
| Maritime NZ (Part 19 / MOSS) | Yes | No |
| AI photo-to-SMS auto-fill | Yes | No |
| Auto-populated SMS sections | Yes | Manual |
| Daily ship's logbooks | Roadmap | Yes |
| Crew induction app | No | Yes |
| Free tier | Yes (full SMS, 1 vessel) | Yes (logbook focus) |
Comparison reflects each product's general positioning as of June 2026 and our own assessment — always check current features and pricing on each provider's own website. "Offshore SMS" is a trademark of its respective owner; SMS Builder is an independent product and is not affiliated with or endorsed by it.
The single biggest difference is who does the writing. With most tools — including Offshore SMS — the SMS document is still something you assemble yourself, even with helpful prompts. SMS Builder flips that: you enter your vessel once, and a compliant, survey-ready SMS builds itself around it. Change the boat, swap an engine, add a life raft — the document updates with it.
The AI photo filing is genuinely unique. Snap the data plate on a fire extinguisher and the model, serial number and expiry are read and filed under the Safety Equipment Register automatically — no typing serial numbers off a cylinder with a head torch.
Credit where it's due. Offshore SMS has years of polish on the daily-operations side: unlimited free logbooks, maintenance scheduling, crew self-induction, a real-time fleet dashboard for owners, and reliable offline access when you're out of range. If your week is dominated by logs rather than the SMS document, that's real value.
The two aren't really rivals. Many operators run SMS Builder for the SMS document and a logbook app for the daily logs. Pick the tool that kills your biggest weekly time-sink first.
Both have free tiers, so you can try before you commit. SMS Builder's free plan gives you a complete SMS for one vessel; paid Skipper, Fleet and Consultant tiers unlock multi-vessel, AI extraction and consultant features. Offshore SMS's free tier centres on logbooks, with paid plans for fleets and an optional human-built "Drop-in SMS" service (around AUD $500). Always check current pricing on each provider's own site.
For operators who want the SMS document written for them — auto-populated and kept current — SMS Builder is a strong Offshore SMS alternative, and stands out for its AI photo-to-SMS filing and full Maritime NZ coverage.
Offshore SMS is Australia-focused. SMS Builder covers both AMSA and Maritime NZ (Part 19 / MOSS), so it suits NZ and trans-Tasman operators.
Yes. Start a free SMS Builder account, enter your vessel details, and your SMS auto-populates. You can keep using a logbook app alongside it.
