As I understand polars, they are saying that the speed on the curve, is the best you will do in those winds. They are not saying that you can always go at the high of a point sailing. So if I understand what you are asking, yes, sometimes you can not point as high, nor want to because of sea state.
I have seen polars with different sea state comparisons too. Then there will even be different rig configs depending upon sea state also. IE, a full main and 110 vs a single reef and 155 for the same wind condition, one being better in 3' chop, the other in 1' waves. Or as I saw once for the V70 follks 40-45knots of wind vs how high the waves were, they had 3 or 4 sail opions, from single to triple reefs with varying jib sizes.
Thanks for that follow-up. I've never seen those polars with the different sea-states factored. It makes sense and would make them much more useful.
As it is, it's difficult enough to find ANY polar diagrams for older designs. But they seem to be more readily available for many of the newer designs. Where did you find the V70 polars? They would be interesting to peruse.
