You might try the manufacturer or a better bet would be the designer
if it is not an in house design. The makers are reluctant to post polars with true and apparrant wind
speed and angles with half load or full load. Why would a maker ever want to publish an upwind VMG's of 3.5 knots in 20 knots of breeze? The speed moniker is tarnished when sailors see that.
seems to be the exception but even those polars do not seem fully explained to me. It looks like the Fastcat 435 has an upwind VMG of 8 knots when empty and 6.5 when loaded for cruising. The Catana 431 is probably somwhere between the fully loaded Fastcat and the Privlage 445 that has a VMG of 3.75 upwind in 20 knots. Good news though, cats are in their element when the twa is 135 degrees, just keep reaching?
Also, US Sailing may have the polars if any were measured to race
