Calypso was launched as Arieto (January 1971). Arieto was campaigned very hard up and down the US East Coast (SORC, Onion Patch etc.). In the late 70's it was sold to the Great Lakes and raced hard as Phantom then Esta Es.
When we (the co-owners) got Calypso to Seattle in 1999 we found the hull had small localized fractures just forward of the mast, at the front of the keel stub well. The fractures were between layers and not visible inside or outside. The indication of trouble was a slight seeping of water. We figure all the years of hard racing with the powerful sail plan pushing her into offshore seas with the backstay cranked to 11 stressed the solid glass and "orange bog" type filler in that area. We chipped out the failed filler, ground down the glass and re-laminated (and built up) the hull in that area. In the space once filled with the brittle "orange bog" we used ground glass fibers and resin as the filler. Now there is no sign of flex there but we are still careful with the backstay and sail loading in big seas. The early 70's "Limited Edition" 43s have longitudinal stiffeners made from plywood (they look like fore and aft bulkheads) that help with stiffing the hull but I am confident the back stay and a big wave could still cause flex/bend. A C&C 39 that I sailed many miles on had a hydraulic baby stay tensioner. I recall being able to lock someone in the head by pumping up the pressure distorting the deck and bulkhead. One of the stiffest hulls I have sailed was a cold molded, Kiwi built Tim Barnett design. On that boat I made several offshore passages in weather that could be described as foul. Sleeping in the port aft quarter berth I could feel waves that struck to strb bow as if the hit was next to me. Great boat, I would sail it anywhere except in ice.
