The C&C 25 was first built because of the success of the C&C designed Mirage 24, which was a very good sailing boat of her day in most wind conditions. The C&C 25 wanted to have similar sailing characteristics and speed with more room. Hence the original boats had similar swept back keels, but later models changed all around. Back then, when your boat was built, they were good, quality boats and C&C touted their patented hull to deck joint as being the best in the industry. Enjoy your vessel.
