Definitely agree with the anchor. Not only is even the slightest breeze a pain, but any current or waves will make you constantly be correcting the positioning. And one you might not realize, if you are throwing baits with resistance to them like a crankbait, spinnerbait, etc...it will pull the kayak towards it as you retrieve. So if you are trying to fish, say a laydown with a spinnerbait...it will be pulling you towards the lay down and before you know it, you'll be on top of where you're trying to fish. It's a fight even with a pedal drive. An anchor or even a makeshift powerpole (if in shallow enough water) will help. Some people will keep a long pole and stick it down through a scupper hole and drive it into the bottom to hold them in place while they cast to various targets in an area. Otherwise, an anchor is a must. You don't need a heavy one. One of those 3 lb ones does just fine.
