Hello,

where can I find the polar table for my 385?

I find this polar very optimistic
the polar mutilated by 0,85 is closer to reality

I'd agree this looks optimistic, especially at higher wind speeds when my experience is that the sea state holds back increased boat speed.  The table suggests only 3% loss in 2m waves but I recall much greater loss.
Having said that, I had many long passages, including a memorable 18 hour crossing of the North Sea where I averaged 7kts.
I used the official Hanse predictions and extrapolated data for the limited table that the B&G accepts, but this is not a full polar.

Also see the 388 thread which will have very similar characteristics.  I do know that Mikael/Charlotte has comprehensive data from his own passages and he has posted there.

I'b believe it if it was apparent angle, we can get to 31 apparent, but not 31 true
