[quote=samc99us]Greg,
Are you sure that is a Nacra 20 and not a 6.0? 1996 is pretty old for that platform, oldest I know is 1997. Lots of details here: http://www.catsailor.com/forums/ubbthreads.php?ubb=showflat&Number=174911
I'll re-hash the rear beam and for that matter front beam connections. These areas were beefed up around 2000/2001, but are okay in original shape if not beach launching/landing/pounding into 30 kt breeze and associated sea state.
Check if the decks have spider cracks and/or are soft. Huge pain to fix.
Sails are expensive, high performance mylar sails and you're adding a $1000 spinnaker to the mix.
End pole snuffers are fine but expensive.
Rudder systems are a bit of weak spot on these boats, castings and rubber fittings do fail with age/abuse/neglect. The updated Nacra 17/ F18 Infusion parts will fit, but be warned of sticker shock. Also, gen1 (thin rudder blades) vs. Gen3 Mk. 1 or Mk. 3/4 (latest Infusion blades are Mk. 3/4, some of the 20's had Mk. 1 Gen3 blades installed which are just fine) rudder blades do handle a bit differently. I've sailed them with all the blades, Gen 1, Gen 2, Gen 3, the 1's are fastest, 3's best for buoy racing, Gen 2's work just fine surprisingly but are a bit more prone to cavitation than the 3's and not as prone as the 1's. Check the upper hole where the upper casting (the one that attaches to the tiller arm) goes, those have been known to snap off if you come into a beach without the blade locked, namely on older Gen 1 blades.
Daggerboard, check what repairs are needed. Minor dings and nicks aren't bad. If its a structural failure, be very cautious, I'm not sure if spare boards exist, I do know none of the new Nacra boards (F16, F18, N17) will fit the cases (too narrow). Maybe Wildcat boards will go in with some trunk mods.
Upper carbon caps on masts have gone bad (UV damage in the sun) and there are no more spares AFAIK, replace with, wait for it, heavy aluminum.
I'd say that vintage in that shape is probably $3-$4k with a trailer. A 2006 in pristine shape, Tybee 500 winner, two sets of sails on $4k trailer setup sold for $10,500 a few years back. These are phenomenal boats, especially if you find a later model with good sails and such, but they are top level race boats and used parts aren't what they used to be.[/quote]
