Good day.
Attached here are the polars for a C&C35-3 (Howard's in particular, but
should be generic...). The polars are for a 135% jib and a spinnaker.
This is in the format Raymarine's Lighthouse software will use, the
format is wind speed along the top, angle on the side.

120 6.284 6.862 7.276 7.612 7.888 8.294
135 5.663 6.466 6.952 7.345 7.691 8.297
144 5.071 5.719 6.427 6.898 7.286 7.967
150 4.733 5.712 5.966 6.54 6.944 7.684
165 4.165 5.08 5.933 6.43 6.839 7.539
180 3.887 4.765 5.597 6.287 6.765 7.488
So for example at 70 degrees in 14 knots of wind the boat should have a
target speed of 7.189 knots.
The attached file is small enough it should sneak through Stu's site.
And a thanks is due to Howard Paul for providing the data.
cheers!
