I love fishing from a kayak. On slow days, it is really relaxing, but when the fish are biting, it's a ton of fun. My kayak is a recreactional touring kayak, so the bigger fish can really affect the way the boat handles. I have some that felt like they could pull it right over.
My dads kayak is a wider and longer sit on top kayak that I can stand on and cast. That thing is a perfect fishing tool.
Im hoping to get one like it in the near future to bring down to florida and see if I can land some big game species and shark on it.
I tend to have better luck from the kayak because it gives me more spots to fish. The harbor I fish out of has a bunch of places to go, and I can go off shore if I feel like making the effort.
There are a lot of hardcore fisherman using kayaks to get to the fish nowadays, and theres tons of info out there.
I'm hoping to start up a charter/guiding business someday, and I think kayaks are going to be a huge part of that.
If you get a chance in key west FISH THE FLATS!!!!! Its some of the best and most challenging fishing around, and it can be a blast.
