Nacra 5.0

I am looking for a Nacra 5.0 and have a couple questions. Does anyone know they changed anything from 1982 to 1987? I saw a post here that the mast base was changed, but anything else? Does it come standard with a roller furling jib or does the jib have battens?

I am 180 pounds and am looking for a boat that I can sail solo in 15 mph winds or take out the family for a casual sail on Squam Lake in New Hampshire. I have sailed a Trac 16 for about 12 years and am looking for more performance and high volume hulls. Thanks!
I realize I made this post in the wrong forum - please see the new post in General Sailor Talk. Sorry!!
