I have an Excellent condition Nylon Main sail and cover made by North Sails custom built for a Columbia 26 MKII. It has Columbia LOGO, battons, leach lines, 2 reefs.
Aluminum boom with gooseneck, reinforced with internal aluminum tubing, boom vang, external outhaul hardware.
Update, the main sail was recently sold. The boom is still available.
How much are you asking for the boom, and is it in good shape (straight etc)
