I owned a 1977 C-27 #3438) for about 7 years and primarily sailed it on San Francisco
Bay. This boat is great for near coastal cruising and believe it or not, two have circumnavigated.
You didn't mention what year your boat was, but if it is an older model check the anchor
bolts for the shrouds. The originals were bolts with fender
washers and they break. Also the spreader brackets were originally made of aluminum
and were known to fail. Finally check your chain plates. The originals have no backing plates
and are bolted to marine plywood
, which over time tends to compress.

I had a lot of fun on that boat and have great memories... Good luck with your trip!
