Our 43 is a very well behaved boat on a reach or run. In stronger winds we have seen surges or possibly short surfs up to the 13/14 knot range. The wave size is important for this to happen. Flat water in 30 TWS Calypso will close reach in the 11 to 12 knot range but the rig will be fully loaded up. If the helmsman is caught snoozing as a gust comes through there may not be enough rudder traction to prevent a gentle spin out. I heard a story from the owner of the 1974 43 “Epic” (black hull, notorious around the PNW in the 70’s and 80’s) of seeing 18 knots boat speed while racing in the Southern Straits of Georgia around 78/79. That race saw winds in the 50’s and big a** seas. I believe the 18 knot story is plausible. The rig load as that surf ended would have been impressive. I sailed 2 Transpacs on a 1974 C&C 39. In both races we would see downwind surges or mini surfs especially in stronger trades with the blooper up. We would get excited seeing 12 knots on the steam gauge and the boat required some careful helmsman ship when the surge ended and the rig loaded up. On non-C&C, modern lightweight designs (ULDB SC 40 and NM 68 and custom fast cruisers) sailed on offshore races and deliveries I have experienced extended surfing and planing including easily controlled and sustained speeds up to 24 knots. This type of surfing and planning is different than what I have experienced on classic C&C designs. Having said that, if I was planning an offshore voyage I would prefer my 43 to a lightweight speedster for its sea kindly motion and ability to keep the crew safe in all conditions. When sailing offshore, short-handed in very fast lightweight boats the crew must watch for debris and actively handle the boat in all conditions. A classic offshore C&C will, on average, be slower, but its characteristics will help care for the crew’s safety in difficult conditions.

Not a definitive analysis, but my recollection is that the older CCA type hulls, C&C 35s, 43s, and certainly the 61s were better off the wind than the later IOR influenced hulls, which were better upwind than the older boats. However, it would be interesting to hear from owners on that subject.

Years ago I recall talking to Rob Ball about the importance of prismatic coefficient in surfing performance but I was remiss in not asking what C&C models have the strongest surfing potential. Thank you Dave
