We give 9 seconds to the C&C 33's on Lake Erie PHRF. Long downwind legs in light air would certainly favor the C&C's but you should crush them to weather and on tighter reaches. Our A sail has helped. We don't consider the C&C's a threat. We appealed (and won) the 3 seconds on the pole since most one design boats such as the Hobie 33's aren't penalized for oversize poles.
