After reading several posts which are very useful to me, I would like to share my happiness and it is my first post!
I caught 2 Bonitos (Tuna) using trolling method in the Hobie Tandem Island (Catamaran/Kayak). My fishing gear is Shimano Terez rod and Shimano Saragosa reel.
I agree with you! So I have to pay extra attention to the school of fish which is very likely to attract other big fish .. SHARK!
Below is the North Head in Sydney the weather was calm.
