Vela-Navega is an independent brand owned by Luis and Iris, combining many years of cruising experience with the development of practical marine electronics.

From 2010 to 2025, we owned a Beneteau Oceanis 40 yacht called Margarida. During those 16 years, Margarida sailed along the Atlantic coast of Portugal, through the Strait of Gibraltar, the south coast of Spain, the Balearic Islands, the south of France, Corsica, Sardinia, Sicily, the south coast of Italy, Croatia, Montenegro, Albania, Greece and Turkey. These pages preserve the story of Margarida, our voyages and several onboard projects.

A major focus of Vela-Navega is now the design and development of marine data multiplexers. Drawing on Luis’s experience as an electronics engineer, professor and sailor, these devices provide practical connections between marine instruments using NMEA 0183, SeaTalk1, NMEA 2000, USB and Wi-Fi, depending on the model. The latest development is Nme3Pro, supported by detailed documentation, firmware updates and direct assistance through our forum.
