like the others said....rarely will you get to keep your catch ....unless you're payin' a chunk or you work it out with the crew before you go...they mainly depend on the money they make from selling fish not the fares ( 'ahi goes for $25/lb during winter you know)....so they will only be willing to part with a pupu/manini size amount most of the time...you guys should think about shore fishing too while you're there, though...150 pound ulua have been caught off the beach on maui , you know....and it don't cost nothing...no fishing license needed....just bring some gear....
