I fish from both a canoe, and a kayak. These are the ultimate adventure vehicles.

I see no problem with standing in a canoe, if it's done properly. It is sometimes necesary to stand in a canoe, to scout the water up ahead, etc....

A kayak is different, because you can completly change directions in less than half of the boat length, come to an immedeate stop, or instant reverse, go over a 20' waterfall and come out unscathed, etc.....something impossible in any other type of watercraft. Kayaks are unsinkable. I crash right over rocks and trees in the river all the time.

You can get into places impossible for other people to fish. You have the right boat. Just have fun with it.
