Why were king ferdinand and queen isabella of spain willing to finance columbus?

Because they wanted him to toddle off to Florida to see if Disneyworld was all it was cracked up to be, dear Huy. Far better to send him off with a camcorder and a few dollars in his pocket. One personally feels that Disneyland is far superior but by the time the wastrel had returned they had already built Eurodisney in Paris.
