I used a similar one without sides.  I used tie downs in front and back from the metal poles to boat.  Never moved.  And I could still get in and work on the boat if needed.  Or sit there and drink a beer.  But I did worry every time we had a wind storm.  I live in pa on the side of a mountain so maybe not as much wind as u jersey guys?
