E-381 P measurement...?

[Tombee]

I found two different P measurements for my E-381; Sailboat data has it at 42.2’, literature I found on my boat has it at 43.25’. Anyone know the true value?

Either figure will do for an estimate of sail cost or other planning.

But always measure yourself when it matters. It's easy, and published figures are intentions, not reality.

Thanks. I’m ordering a cradle cover/lazy jacks for the main and will ask the manufacturer how critical the P value is for a proper fit.
