After the California exploration ships were built, Cabrillo and his mixed crews of conquistadors, Spanish and untrained Native American sailors totaling about 200 men, carefully made their way north from Navidad, Mexico up the Pacific coast starting on 17 June 1542. They took enough supplies to last about two years. The combination of the south flowing California Current and often opposing winds made progress north up the coast agonizingly slow. The small, rudely made open boats with only partially trained crews caused the crews to suffer miserably in the storms they encountered on their way. After landing several times on the Baja California coast for water, wood and whatever supplies they could scrounge they finally, after traveling one hundred and three days, entered San Diego Bay on 28 September 1542. They continued north up the California coast encountering many Indian villages using Native American "tomols" (ocean-going stitched canoes). The continued north up the coast possibly as far as Point Reyes California.
