I have been pondering a kayak for some time now... dual purpose fishing, but mostly hunting. Was looking at an Ascend H10 for ability to haul a little more gear. Being a large American, i'm pushing weight limits on most (bargain) kayaks minus gear. Let's just say the CFO would not approve a Hobie unfortunately. Most of the public tracts around me are mainly moving water with substantial currents in certain sections. Having never been in a kayak before, and understanding endurance plays an obvious factor (i'm not out of shape, but i'm no marathon runner), what kind of currents can make upstream travel possible? I've taken said rivers in a canoe (2 people) and definitely glad we parked another vehicle downstream! Ultimately, is kayak travel easier or comparable to canoe travel? Thanks.
