New to wakeboarding, questions about the boat aspect of it

[madd_wakebrdr]

i am very new to wakeboarding, and i have a couple q's about my boat(bayliner 18.5). i do not have a tower on this boat, do i really need it. also, i was looking at towers and i saw one that was just a 7' pole tied to the front of the boat, how good does that work? :? :?: q #2: got up yesterday and i was sliding all over the place, and i was confused which way you should lean right at the start . q # 3 foot placement, i had my left foot on an angle to the right of the boat and my right foot perpendicular to the board( i am not a goofy rider), might the binding placement in that senario have anything to do with the swerving?
