Charlie's numbers are a good example of what I was saying, if you adjust Charlie's displacement from the way it was calculated during CCA (tanks full, and with normal gear and supplies aboard) vs the way it is done today, dead empty, and look a more modern design, something like a Hanse 350, or Beneteau 36.7, there are probably only a few hundred pounds difference (maybe as much as 4-500 lbs) between Charlie's boat's displacement and the more modern designs. But when you look at the waterline lengths of approximately 31.5 and 30.6 feet respectively, you can quickly see why they have L/D's of 181 and 209 respectively vs Charlie's 344 and that it has little to do with the overall weights of the boat.

And as Charlie says he actively owns and sails his boat in a range of weather and he likes his boat. I seem to spend a lot of time jumping back and forth onto boats that represent a broad spectrum of sailing history, CCA to IRC. The heavy weather liability of the old CCA long overhang, narrow beam designs becomes quickly aparent after you do that for a while.

One other minor point, Charlie's boat has comparatively long waterline length for a CCA era boat (LOD/LWL=.76) as compared to more typical designs like the Black Watch 37 (.69), HinckleyPilot 35 (.71), Bristol 32 (.68), Triton (.7), or Ariel (.71). She is also a proportionately beamy for a 35 footer from that era as compared to a more normal CCA boat like a Pilot with a beam of 9.5' vs Charlie's 10'.
