[quote=P.M.][quote=ADixon][quote]16 to 1 and my wife can pull the head out. That's what we used on our 91 5.5SL, 97 sails, 420lbs on the diamonds and 1.75in of spreader rake, sailing at 295lbs crew weight. The downhaul would bend the snot out of the mast.

Ron,
Were you using standard Nacra5.5SL mast and sail? I always wanted some prebend like on F18, but was not sure the standard mast and the sail can handle it. Can you share more of your experience with that?[/quote]

Andre,
Did we not meet at Juana's about 5 or 6 years ago? You were staying with Mike C.   . . .anyway . . .allow me to chime in.

I had the same extrusion on the 5.8NA (the 5.8 and 5.5 share the same extrusion).  I purchased a new high aspect ratio main, very much like the F18 or N20 mains.  I upgraded the downhaul and basically had the same set up that is on the f18, N20.  The performance was phenomenal.  The extrusion held up fine and worked as designed.  It took a little bit of time to get the diamonds, rake, tension dialed in because there was no one else with the set up for reference.

So, the short answer is yes, the mast extrusion will work and perform well with a wide range of prebend and trim induced bend. <em>edited by: mummp, Sep 29, 2010 - 01:42 PM</em> [/quote]
