Great post. I've discovered these challenges over the years from foot, kayak, and boat, and they're always worth discussing in the interest of uncovering nuggets of new advice or perspective.
Most of my "boat" fishing the past two years has been from a kayak, and even then I mostly use the craft to get from point A to B, then get out and wade fish. But there have been plenty of situations that have presented themselves while fishing from the kayak to learn that it doesn't behave like a typical boat, and presentation is far different because of the much lower profile. The flip side to the presentation challenges is that because of a kayak's stealth, long presentations are rarely needed.
Thanks for starting this thread.
