Re: C&c 37+
Two reasons, really, one objective and one subjective; objectively, because it seems to be a design issue rather than a maintenance issue. If they goofed on the install, it's going to take more than a shot of teflon spray and a new furling line to fix it.
Subjectively, if I'm buying a performance sailboat, I want the performance... even if the furler could be fixed up, at the end of the day I would have dropped a lot of coin fixing something that is still going to slow the boat down.
Obviously some folks won't care (someone chose to install it in the first place, after all) but I imagine most people looking carefully at C&Cs probably do.
