There is speculation over the total cost of the journey of the Discovery.  It is said that Luis de Santángel, backed by Seville merchants, lent the crown the sum of 1,140,000 maravedies.  The admiral contributed 500,000 maravedies, which were supplied by the Italians Berardi, Jacobo di Negro and Luigi Doria.  The ships were acquired at a price equivalent to 360,000 maravedies.  The Pinzón brothers, especially Martín Alonso, were key in obtaining the participation of the Palos sailors, who doubted the success of the journey.  In addition to sailors from Andalucia, Seville, Basque, Italian and Portuguese sailors joined.
They stored enough water and foodstuffs (flour, crackers, salted fish, bacon and wine) for a six-month period.
