I had to take my mizzen staysail in to the loft yesterday to repair a rip in the seam. The guys there were telling me that most staysails have a "wire" sewn into the luff. I have no clue (pardon the pun) how a proper saysail should be constructed. Of the Ketch owners out there who have one, how is your's constructed, wire or no wire? Also, what sail cloth is it made from, Dacron or Nylon - weight?
