I'll try the N5.2 first to see if that works for me, if that proves too daunting (or I can't find one that isn't bent, soft or full of holes)
I don't think there are any nacra 5.2 in NL that are younger then 15 years. Most are from the 80's even, about 20 years old. While I owned and sailed a 25 year old boat myself alot I feel that finding such old boats in relatively good condition is rare. Therefor I think finding yourself a decent 5.2 in NL is setting a high goal, just because you want to have daggerboards.
I haven't seen a nacra 5.2 in years.
