Change your times and rates For say: 5 hour --500.00 2.5 hour--300.00 just using numbers ofcourse, I dont even know what charters cost. That way you save fuel and fish plus make a little extra and dont feel like you are rippen the clients off. Then its the clients choice. Just explain if limits have been comming pretty easy or not. You can also take more trips in a day if they do 2.5
