Hi again 49er,
So according to the TEXEL site:
http://www.texelrating.knwv.nl/The FX-1 no-spin is 324 lbs and the Nacra 5.5SL is 381 lbs
That's 57lbs lighter, which would explain my perception of it feeling lighter on the beach. (The 5.5Sl is a fantastic boat too, so please don't attack me 5.5SL owners).
That sounds believable to me. Though slightly disappointing, I'm still happy with the weight and quality of the boat.
I would certainly consider owning an A-Class also, and don't understand the opposition to it in this thread. I purchased the FX-1 for my own reasons, as anyone should. (mainly the two-person capability in all conditions).
Thanks for all your help and accurate information provided so far!
Steve
