C27 can take it
I've saled my '74 OB std rig 27 on the northern California coast for about 10 years now. Max winds I've experienced are about 30 knots (a couple times). With a double reefed main and 95% club jib, the boat handled it very well. Once we were beating into 8-10ft seas going north from San Francisco to Bodega Bay. The boat was well balanced, a little weather helm, but not too bad. We were going straight into it for about 6 hours, and would tack whenever the VMG on the GPS dropped below 3.5 knots. I remember going down below and taking a nap for about an hour mid-afternon, we were under good control.Also have done a roundup/down when DDW in 30 knots of squirelly wind under the spinnaker. Had about 3 inches of green water above the top of the primary winches after the round-down. Didn't bury the spreaders, but were at probably 65-70 degrees heel. But when we blew the spin sheet, she came right back up. Had a mess down below to clean, though...Another time, however, we were under the kite going from SF to Monterey in 25K + of constant winds. We averaged 7-7.5 knots VMG for 6+ hours. Always perfectly under control. I thought maybe the autopilot could have driven us it was so easy. When properly sailed and rigged, the C27 can take most anything most of us might want to throw it, short of "The Perfect Storm".Good luck!
