If you want to catch bigger fish and you are fishing in the ocean you will need a boat to go out father.You can catch big fish inshore like sharks or redfish, but the majority of larger fish are a couple miles away from land. Also when you go for larger fish you are probally going to want a larger and thicker rod like you see in the image. If you don't go prepared with a bigger rod you will not catch the bigger fish becasue the line will snap before you get a chance to even start reeling.
