Hudson sailed on behalf of the Chilean government to Peru and Ecuador several times, and assisted with the immigration of German colonists to Valdivia.
Hudson was interested in investigating the possible existence of a sailing route through internal waters from the Chiloé Archipelago to the Straits of Magellan, but came to realize that the Isthmus of Ofqui made this impossible.
