Find out what your boat can really do.
Every boat sails differently. That's why Smartboatia gets to know your boat better with every trip. Your sailing data becomes your personal polar, an analysis of your tacks and live trim tips on board that show you where there's more speed to find.
- Polar from your data
- Live trim tips
- Tack score in seconds


Understand why your boat gets faster.
Looking at speed alone isn't enough. What matters is how fast your boat could actually be in the current conditions. Only the comparison with your personal polar shows where there's still potential.
Smartboatia analyses your sailing data automatically and reveals connections that would otherwise stay hidden. So you understand better what really makes your boat faster.
You're sailing 6.4 knots. Your boat can do 6.9.
Upwind in 14 knots, Smartboatia shows you live how fast your boat could be according to your own polar. So you see at a glance how close you're sailing to your boat's potential. Adjust your trim and see right away whether it works.

Your boat learns. You benefit.
With every trip, Smartboatia learns something new about your boat. Instead of generic manufacturer data, your polar comes from what your boat actually sailed.

- Insights & analysis
What you get
Personal polar, with a Standard subscription, download it as .pol or CSV and use it in your routing app
Trim recommendations, for main and headsail, based on proven sailing principles
Manoeuvre analysis, follow every tack and gybe in detail
Live against your polar, target speed, target VMG and polar performance in percent
Polars, trim tips and tack scoring need a wind sensor on board. We calculate your polar once a week in the Smartboatia Cloud, so your Hub needs to go online now and then. The app shows trim tips while your logbook is set to “Sailing”. Your polar learns from legs you mark as “Sailing” in the logbook.
Your polar. Not the one from the brochure.
Many apps work with polars from a database that you have to adjust yourself, or charge an expensive add-on subscription for it. With Smartboatia, your polar comes from your own sailing data, on every plan. Plus trim tips and tack scores live on board, all in one app with your logbook.
How Smartboatia gets to know your boat.
Every trip brings new data. Step by step, it builds an ever more accurate picture of how your boat sails in different conditions.
- Step 01
Watches every trip
Wind, speed, heel, course and manoeuvres are recorded automatically. Just set “Sailing” in the logbook when you're sailing, and that stretch goes into your polar.
- Step 02
AI gets to know your boat
Every week, Smartboatia recalculates your polar from all your sailing data: for 13 wind speeds and 19 wind angles, the way your boat really sails. Once learned, every value stays.
- Step 03
Shows you what works
Clear analysis: compare your tacks, discover your personal polar and find out in which wind and on which course your boat sails best.

“We have been using Smartboatia for two years on our circumnavigation and don't want to sail without it anymore. Based on the recorded data, we make better decisions while sailing. It gives us security and makes a lot of things easier.”
Every trip brings new insights.
The Hub combines its own sensors with data from your onboard instruments. Every trip deepens the understanding of your boat and makes your analysis more accurate over time.
