Since those are all rounded numbers I wouldn't put much faith in them. I'm not a Cigarette historian but recently I've been reading everthing I can find since I've been shopping for a used T.G..
There are a number of topics on weight and carbon fiberand/or Kevlar or convential layups and associated weights. Also remember there are different cabin configurations.
This could cost me but I'd bet a cold beer of choice that there are less than 20 Cigarette owners on this board that have a certified weight scale ticket with there boats weight shown.
There are guys here that have far more knowledge than I and are extremely helpful. May want to repost in Cigarette forum.
