Have fished out of there on two different occasions. Managed one AHI on one of the trips. And that was only after I asked if we could throw out a line for "bait". I wouldn't do anymore than a half day. The fishing seems spotty at best. But if you want a chance at BIG marlin then Kona is a good bet. I wouldn't recommend either of the two charters I used and unfortunately I can't remember their names. A buddy of mine that lives there set up the trip both times. It is beautiful water and great to look back at the island and see the volcano from out in the ocean. Good Luck.
