Zarzuela is 1972 Hull No.224 bought by me 12 years ago. Your boat is a NC33 Mk1 I think. Different hull, keel, larger rudder (mine is mounted on a skeg) higher masts, external cockpit, larger sail area etc. yours has much better sailing qualities than mine.
I do not know whether Nauticats are supplied with a deviation table for their type. I “swung ship” to check the table I had.
