Turn Data Into Speed

How fast was your boat today, really? The log gives you a number. It does not tell you whether that number is good. Smartboatia learns from your trips how fast your boat can go in which wind, and shows you where there is more speed to find.

Why speed alone says little

Six knots can be a strong result in light air and rather average in a fresh breeze. What matters is how fast your boat could be in the current conditions. That is exactly what a polar describes: the possible boat speed for every combination of wind strength and wind angle.

Polars from your own trips

Many apps work with polars from a database or a rating certificate. They rarely match your boat, your sails and your load. Smartboatia takes the other route: on every trip the Hub records wind, heading and speed and builds your boat’s polars step by step.

• No rating certificate needed. When you sail, just set “Sailing” in the logbook and the distance feeds into your polar.
• The more you sail, the more accurate the polar gets.
• You always see how close you are to your own best.

Trim tips for your sails

The app also gives you live trim tips for main and headsail, matched to wind and course.

What each tack costs you

The Hub detects tacks and gybes automatically. The tack score then shows how many seconds each tack into the wind cost you. Over several trips you can see your crew getting into the groove.

Only when you know how fast your boat could be can you tell whether you are sailing well.

How to get started

1. Install the Hub and connect it to your onboard electronics.
2. Sail as usual. The Hub records automatically.
3. After a few trips, open sailing performance in the app and look at your polar.
