 Using the financing secured from the Merchant Adventurers , the Colonists bought provisions and obtained passage on two ships : the Mayflower and the Speedwell . They had intended to leave early in 1620 , but they were delayed several months due to difficulties in dealing with the Merchant Adventurers , including several changes in plans for the voyage and in financing . The Congregation and the other colonists finally boarded the Speedwell in July 1620 in the Dutch port of Delfshaven .
