Re: CS27 vs C&C27
The CS is a bit bigger boat - 1/2 ton more Disp, 1/2 a foot more beam & a foot more W/L.
Both are good old boats but I find the CS boats seem to hold up a smidge better over time.
There are a couple of donated C&C 27's at Harbour Yachts - or are those the ones you referred to?
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
