Mike,

Thank you for your help, my Nacra 5.2 is still completely set up with the non-captive system with the small ball. I did own a Nacra 5.7 before and it was with the captive mast system so I can tell the difference between the two systems.

I almost did the upgrade last year but I think that the one person mast stepping will be easier with the non captive system and the vertical pull technique.
