Established in 1950, Inter-Island Sportfishing is the oldest deep sea charter fishing business on Oahu. All of their Oahu big game fishing tours depart from Kewalo Basin Harbor in Honolulu. They offer three private charters aboard the Maggie Joe, Ruckus and Sea Hawk sportfishing vessels, meaning you pay one flat rate for your group of up to six people. If you're looking for a shared charter (to buy single tickets), check out their shared fishing trip option. Select one of these great Inter-Island Sportfishing charters below.
