You know that geometric symbol, often adorned with artistic details, that we see tattooed on sailors“ arms, engraved on old maps, or embedded in the floor of historic squares like the one in Belém? To the less attentive eye, the Wind Rose is just an aesthetic element of nautical inspiration. However, to those who live the sea, it represents humanity's first ”GPS" and the ultimate symbol of orientation and survival.
In this article, we will delve into the history of this invisible code, understand how it shaped the Age of Discovery and why, even in the age of satellites, the Wind Rose continues to be the moral compass for any sailor – and any event organiser who refuses to lose their bearings.
The Origin: When the Winds Had Names
Before magnetic compasses or digital navigation systems existed, Mediterranean sailors navigated by the winds. Each direction wasn't just a cardinal point, but a force of nature with its own personality. The Wind Rose was born out of the need to map these directions so that routes could be safely repeated.
Originally, the Wind Rose did not indicate North, South, East, and West. It indicated the directions from which the main winds blew. In the Mediterranean, for example, we had the Tramontana (North), the Levante This, Sirocco (South-east) and the Libecio (Southwest). Knowing how to identify the wind was the difference between a prosperous voyage and certain shipwreck. For the Portuguese navigators, who later explored the Atlantic, this knowledge became the basis of the cartography that allowed Portugal to “give new worlds to the world”.
The Anatomy of the Compass Rose: Cardinal, Intercardinal and Secondary Intercardinal Points
What are so many points for? A complete compass rose is a work of mathematical precision. It is divided into:
- Cardinal Points North (N), South (S), East (E), and West (O/W). These are the principal axes.
- Side Points Northeast (NE), Southeast (SE), Southwest (SW) and Northwest (NW). These points arise from the bisection of the angles of the cardinal points.
- Sublateral Points For even greater accuracy, there are subdivisions such as North-Northeast or South-Southeast.
In practical navigation, this division allows for a thorough reading of a vessel's drift.
On the Tejo, where late-afternoon thermal currents and winds can change the dynamics of a sailing trip in a matter of minutes, mastery of this “compass rose” is what allows our captains to maintain the fluidity of an event, ensuring the ship is always in the ideal position for the best view, without guests even perceiving a course correction.

The Compass Rose and the Symbolism of Success
Beyond the technique, the compass rose carries a strong symbolism of focus and direction.
In the corporate world, where market “winds” are constantly changing, having an internal compass is essential.
Many companies choose this symbol for their Team Building events or strategic meetings in the Tagus precisely for this reason. It represents the ability to find the right path amidst the immensity.
No Seaventy, The Wind Rose is our commitment to total coordination. Just as a navigator needs the compass rose to avoid getting lost in the vastness of the ocean, an event organiser needs a partner to act as their north star.
Why hasn’t GPS replaced the compass rose?
It may sound romantic, but the truth is technical: electronic systems can fail, but the winds and stars do not. Nautical literacy demands that we always know where we are by direct observation.
At Seaventy, we apply this same logic to our operation. We have modern technology and processes, but we never lose sight of “direct observation” – the physical presence at each event, the attentive eye of the coordinator who notices the wind has changed and that the disembarkation needs to be adjusted for the guests' comfort.
The North of Seaventy
When you see a compass rose on one of our boats, remember: it's there to remind us that on the Tagus, there's no room for improvisation. The beauty of the landscape and the lightness of the cocktail are only possible because someone, behind the scenes, masters the compass rose, the tides, and the logistics.
If your aim is to organise a corporate event where nothing goes wrong, then look no further.
At Seaventy, we transform the complexity of navigation into a fluid and natural experience for you and your team. After all, knowing where we're going is what allows us to enjoy the journey.
