Where it sits
How SailTac compares
The professional tools are built around a full-time navigator and reward one. The phone apps are built to be picked up in a minute. SailTac is built for the boats in between — and for the analysis that, on either of them, someone still has to sit down and do.
| Capability | SailTac | Professional nav software | Phone apps |
|---|---|---|---|
| Built for | Amateur + pro racers, performance cruisers | Full-time navigators on campaigned boats | Individual sailors |
| Where it runs | Every phone, tablet and laptop on boat Wi-Fi | The nav station computer | The device in your hand |
| Weather routing | Ten models, coloured per leg by how far they disagree | Multiple algorithms, ensembles and wave routing | Yes, in the routing-focused ones |
| After the finish | A written debrief attributing time lost, with its evidence | Logging, replay, stripchart and polar tools to work through yourself | Race replay and leg-by-leg splits |
| What you can hand someone | A one-click multi-page PDF and a 4:5 recap card | Exported data to build your own report from | A shareable replay link |
| Learning curve | An afternoon, with a demo mode to practice in | Deep, and repays the time a dedicated navigator can give it | Quick to pick up |
Our own summary of the category, written to be useful rather than flattering. Every cell says what that kind of tool is built to do — none of them claims another product lacks something, because that is not a thing we can know from the outside.

Questions
Before you buy
Anything not covered here, just ask — scott@sailtacperformance.com. A real person who races reads it.
- Is it per person or per boat?
- Per boat. One subscription covers every phone, tablet and laptop aboard, for the whole crew. Per-seat pricing would fight the way the product is built — the point is that everyone can see the numbers.
- How does the license actually work?
- You get a license key by email. Enter it once, on any device, and it unlocks SailTac for every device on that boat. It's tied to the boat name you give at checkout, not to a person or a machine.
- What happens when my year is up?
- Your subscription renews and we email you a fresh key to paste in. If a renewal is late, the app keeps working for 14 days with a warning banner rather than locking you out — a license should never be the reason you can't race.
- Does it work offshore with no signal?
- Yes, and that's the point. Fetch the weather and cache the chart tiles for the course before you leave the dock, and everything — instruments, routing, logging, analysis — runs with no connectivity at all.
- What do I need to run it?
- A Windows or Mac computer aboard — Windows 10 and up, or macOS 11 and up · Apple silicon and Intel — and instrument data it can reach: NMEA 0183 over the network or a USB adapter, or NMEA 2000 through a gateway. The installer includes everything else; there's nothing to install first. Crew connect from their own phones and tablets over the boat's Wi-Fi.
- Is there a Mac or iPad version?
- There is a Mac build — signed and notarized by Apple, Apple silicon and Intel — and it runs the instruments and the analysis exactly as the Windows one does. There is no iPad or Android build of the boat computer itself, but the interface is a web app, so iPads, iPhones, Android tablets and other laptops all work as displays over the boat's Wi-Fi.
- Can I try it before I pay?
- Yes — 30 days, every feature, no card. Download the installer, request a trial key, and run the built-in demo simulator on your kitchen table before you ever plug it into the boat.
- What if the season gets away from me?
- If you subscribe in the spring and don't get to race it that season, email us and we'll sort out the next year. We'd rather have you racing with it than holding a grudge.
