Hey krazo84......Welcome to JaxKayakFishing and please pardon the people that want you to pay $2,500 for a "longer fish box"....LOL!!
Please let us know where you live and where you intend to fish, and we will try to offer some suggestions on what types and brands of kayaks to consider buying.....sounds like you are a long way from purchasing one at this time...but that is good to give you time to learn!!
Also, there are only a few people in here who have caught Kingfish in their kayaks, and Punisher who posted above is one of them....but, he DID NOT catch them out of a Kaskazi Dorado......but....I'll bet this summer he will!!

PS: My buddy, SLP053, from Georgia caught a whole bunch of nice kingfish last summer at Panama City Beach, plus one VERY NICE dolphin (mahi mahi) and LOTS of Spanish Macks!!
