Snapped this at the Club. In another post, we suggested that you might consider that:-

• you want to share the stand between two or more classes of boat. For example, Ten Rater, Marblehead and One Metre.
• you are a little on the tall side, or would be more comfortable on a higher level stand

I think this photo is of a Ten Rater stand, with additional keel supports to support Marblehead and One Metre keel positions.

Here it is being used with a One Metre and in the rig tuning position
