Coincidentally, the lake I fish most is also about 10,000 acres. So far, I haven't ventured more than a half mile or so from the launch. The boat is certainly capable of a lot more than that, but since I slow-troll both out and in, it would just take a lot longer to go farther.
My most comfortable cruising pace is about a quick walk, call it 3 mph. I troll at half that. Neither is tiring in the least, and pedaling the Prangler is almost exactly like being on a recumbent bike, effort-wise.
