I had a chance to check on this on two boats and it seems unique. While they may be consistent from side to side that may be from a hoist strap exerting the same pressure on both stanchions. I checked mine,Hull 1057 and a friend's, hull 276 and neither have these deflections. So I'd bet it didn't come from the factory that way. As to what to do? Maybe nothing if it isn't leaking or causing an issue. Good luck and good sailing!
