How are you trying to hookup? With sharks, I'm roughly 80-90% on hookups when we get a bite. The thing with sharks is that they pick up a bait and run with it a short way. Then they stop, eat it, and move off again. Wait for the fish to stop & take off again. Set the hook early into the second run. I think your success rate will improve dramatically.
I know every charter group we had was chomping at the bit to set the hook right away. Most people think they've lost the fish when it stops and start winding in the bait to check it. That's when you loose the fish. Have patience & you'll have shracks.
