You don't need to go far out to catch fish down there - there are definitely half day charters. You can also do some back country fishing in the mangroves.
There are probably plenty of charters in marathon but keep an eye out for Bud and Mary's as you drive down - if it turns out that you have trouble finding a boat in Marathon, you certainly can find one there.
Last time I went to the keys we hit up Islamorada for alternating days of flats fishing for some bonefish & tarpon, followed by going offshore for some permit & mahi mahi. Best of both worlds, can't wait to make my way back someday.
