Yes, its worth the money. Good entertainment. But they don't tell you everything, and they don't all fish the same way. Each captain has their own way of doing things, and they don't even tell each other some techniques. They can be little competitive
But overall, its worth the time. They cover everything from trolling to chunking and will have sessions on specific fish like swordfish and this year bigeyes I'm sure.
Just be aware that with them, its all about the numbers. They are more interested in catching a lot of fish, as opposed to catching quality fish. They rig with relatively light leaders for example. For their business, it's better to boat 20 small to medium yft than 4 over 100 pounds. If those larger fish break off, they aren't concerned. They are after the smaller ones in numbers.
You may want to do it differently, or not.
