Hi again

When sailing, approaching a lay line, I am now calculating the new TWD for laying (in case of a shift).
For example I would say;
Splits 2 and 6 (minutes) laying on 220 (TWD)

This then in a situation where the TWD is 200 and we would lay if we have a 20 deg rightshift. I’m now using “twa to mark” and distracting this from target twa, and adding the difference to the current TWD.

Is there a parameter that is doing this calculation for me?if yes, which one?

Always grateful for your support.

Best regards
Silje
