Kauai offers several charter and day boats that, as usual in Hawaii, get to keep the fish. Most take two to six anglers for half to full day periods at fees from about $75 each to $125 or so. It's advised to check the weather, as the North Shore can get very lumpy. Call 808-245-3564 for ocean conditions. Realize that if you go the big game route, it's unlikely everyone, or anyone, will get a fish. Billfish require an average of 10 trips per trophy boated. So Bob McReynolds Sport Fishing (808-828-1379) seems a good choice as he specializes in light tackle catches. Beach, bay and cliff fishing is very productive with local knowledge. It's possible to get information from local tackle shops. It's not unknown for friendly locals to take you out for some shore fishing if you pick up the lunch and gas. Freshwater fishing in the many reservoirs can require permission, and both the Wailua River and Reservoir off largemouth and peacock bass. If you want 'truck trout' stockers you can find them in Puu Lua Reservoir and some streams between August and October on weekends or whatever -- you read the instructions, bro'.
