David;
In 5 knots the 155 would have a big advantage – in 12 knots not so much. In 15 the Dacron 135 I use now (instead of the old carbon 155) gets me to hull speed just fine. With big winches, the difference in effort from a 135 to a 155 is pretty manageable. So lightweight female crew may not be a significant problem. But the 155 can be persnickety about trim, so the “novice” part of your crew might make a big difference. As I recall, the 36 was like a lot of the mid-70s C&Cs and was driven primarily by the headsail. Your 90s vintage boat likely has a significantly smaller J and is driven by a higher aspect main. What shape is your mainsail in?

I have a 140% UK tape drive genoa I got 3 years ago. My main competitor in Wednesday night beer can racing is a C&C 36 which has a 150-155 racing triradial laminate genoa (no UV protective, kevlar I think). In 5-12 knots of wind, he just powers away from us upwind and he is supposed to be 20-30 seconds a mile slower. Admittedly, he is really good with experienced crew and knows his boat well from years of competitive racing, but I don't ever go faster than him upwind. I fear that a 150% with my crew will be too much too handle much of the time (3-4 lightweight female novices where he has 7-8 big strong guys) but I wonder if the 140 vs. 150 is a reasonable explanation or if a “racing briradial” is that much faster than a “cruising” tape drive?
