My 0.02

I am probably not an F18 connoisseur yet, but am starting to learn what I like and dislike.

Really happy with the build quality of the new (to me) C2 I acquired a few months ago.

Hulls- Really like the quality of the fiberglass layup, lack of stress cracks, etc. Platform with bedded beams seems incredibly stiff.

Rigging- Mast/sail seems to respond well to cunningham adjustments.
- Realize this is not 100% specific to a C2, but grommets on the tramp allow the spin halyard and retrieval loop to be run under the tramp - very clean.

From a handling standpoint, I had sailed both a Tiger and an older Nacra F18 last year and the C2 seems to tack much more quickly. Seems to sit higher up in the water and perhaps have a bit more rocker. Could be true of other newer gen boats with more hull volume/rocker.

Have not had a chance to exercise the service side of the equation, but have heard good things.
