Tartan 41 1972 keel
I've got hull #20 (1972/73). Which one are you looking at (Marblehead)?
Mine got the retrofit keel (7'2", 9,900 balast) with the tall rig. Even with the original keel I think it would be fine unless you were really pushing it in higher winds with the chute up. These are sweet sailing boats.
I did a major deck re-core etc. if you want any feedback.
