You don't list the Nacra 5.5uni specifically, but it is a boat designed for carrying weight (minimum for the sloop, same platform, is 275.) Also, the PN is nice; if you put a chute on it, the D-PN for distance racing is 67.0 compared to 66.6 for the I-17R and no number yet for the FX-One. Also, the 5.5 is about 6" longer and 3.5" wider than the 17R; I can't say how it compares dimensionally to the FX One.
<br>Anyway, I was 260 dry when I got my uni, and was one place into or one out of trophies four of the first five regattas I sailed. (I was very last in the sixth and won the seventh.)
<br>
<br>good luck, and sail fast
