Had a father and 8 years old son from Alaska on a 3/4 day Kona fishing trip. First thing in the morning we missed two blue marlin and time was running out. So asked them if they wanted to extend in to a full day fishing charter and it paid off with the 8 year old boy catching a blue marlin plus a Mahi Mahi.
