I would have to disagree, i have a native titan 12 that i carry 9 - 11 rods on, a ton of tackle, lunch(im fat) and stand all day to fish!
I realize it a troll post but if it wasn’t the issue is he hasn’t owned a fishing kayak. Or at least not a good one.
I'm brand new to kayak fishing. Just bought 2 Sea Ghosts 110 for me and my wife. I've only fished out of it a couple of times and there are some challenges but nothing to difficult to overcome. So far I love it. I'm just starting to learn how I want to set them up, but I do know this...I don't need to bring the tackle store with me. One 3750 Plano box and 2 rods each, a 3lb weight for an anchor and enough water is all I need.
