We installed a new Tuff Luff on Thursday of the NA's after breaking ours restepping the mast. Extrusion 1706-36, no hardware $288 through my sailmaker from Shaefer (possibly discounted considering the circumstances). This is for a #6 Luff tape (check with your sailmaker if you don't know). 36 Feet long, it needed several feet hacksawed off to fit. You'll want a feeder, top and/or bottom spacer. Maybe a top cap, pre-feeder, and Kevlar bumper. See
