Too close to boat

The drowning thread reminded me of what happened a few summers ago.I thought i should share in hopes it might help somebody avoid same mistake i made.With board on i get up to the swim platform to hand something to my wife.We board in a lake not a river.So i feel my board start pulling me under the boat.I wasn't thinking about currents but quickly realized there was one.It took my wife and 2 other's to hold me up and undo my bindings.The board was acting like a sail underwater.I never get too near the boat with board on anymore.A stupid mistake almost cost me my life.Anyway i hope this helps someone avoid that happening.Even if your're in a calm lake there are currents.
