Álvaro de Marichalar in the wake of Juan Sebastián

de Elcano and Fernand de Magellan

Álvaro de Marichalar, a congenial Spanish explorer with a track record of forty sea raids on a personal watercraft (PWC), has set off on the route of the 1519WorldTour2019 expedition, celebrating the 500thanniversary of the first circumnavigation of the Earth (1519 - 1522). It is the greatest challenge ever attempted with such a craft: a tour of the World in the wake of Fernand de Magellan (1480 - 1521), and Juan Sebastian de Elcano (1476 - 1526).


Álvaro de Marichalar left Seville (Spain) on the 10th of August, then Sanlúcar de Barramedaon the 20th of September. After jetting along the southern coasts of Spain, Portugal and northern Spain, he arrived in Guetaria, near San Sebastián, where he paid tribute to Juan Sebastián de Elcano. 


At the beginning of November, Álvaro de Marichalar paid a visit the Yacht Club de Monaco, as a member of the Club des Explorateurs, to present his "petit navire": NUMANCIA, a 155-horsepower BRP SEADOO FISH PROjet ski, specially prepared and equipped for the occasion. Yvan Griboval, President of OceanoScientific, himself an explorer - circumnavigator and also a member of the Y.C.M. Club des Explorateurs, has engaged the OceanoScientific philanthropic association in the final preparations for Álvaro de Marichalar's crossing of the Mediterranean, and then the Atlantic, providing friendly technical assistance to the big-hearted Spanish sailor. Álvaro de Marichalar can now add the title of OceanoScientific Ambassador to his visiting card as an explorer with a mission impossible.
