i dont know the exact regulations but its small lakes normally under 1000 acres, and the main reason i am on one i my wife, she has a fear of water and my love of being on the water so a pontoon boat on the 10 hp lake is the comprise we found, the wakes on bigger lakes scare her and at first it drove me nuts but i have come to enjoy it a lot, to start out no jet skies those are out of control on a normal lake and no 300 hp bass holes, its mostly families and kids, and after i started getting used it it was the people, some of the nicest i have ran across in years and due to the slower speeds i was able to kick back and relax while driving and just enjoy the ride
