All beaches in Hawaii are publicand he can be very productive.I have work in the fishing business covering the Hawaiian Islands for more than 10 years. People want to think exotic and heavy gear went fishing Hawaii but most are wrong. The basics of fishing the beaches of Hawaii, are 6-8 pound test and a half ounce or lighter Kastmaster. . That's it. Don't overthink it. You can use any fishing rod that holds 6 to 8 pound line. I prefer a two or four piece salmon steelhead rod greater than 8 feet. In Hawaii this is called "whipping" . The next tactic that is used for shore fishing in Hawaii is a float and a small one to 2 inch plastic grub. Tying the float to your mainline attaching a leader to the other side of the float and a small hook with a 1 to 2 inch curly tail plastic grab with about a 6' leader. This is a real and splash technique. Very fast-moving and nonstop will attract a bite. I like fishing this way because I can travel with my four piece rods in my checking luggage. Lately I have found that Daiwa, TFO and okuma make the best travel rods. Anything greater than 7 foot will work fine but I choose 8 foot plus as he gives me more distance in casting. Again don't overthink it a Kastmaster is one Luer you can bring plenty of fish .. Excuse the typos, this was written by voice text
