Chinook aluminum wave boom for small to medium sails, black and purple, adjusts from 130 - 175 (the black booms in the picture are sold).  Standard diameter grips, not narrow.  Used but not abused, plenty of rides left on them.  $40.  May throw in a respectable small wave sail and/or a mast base or two too!
