I raced Tartan 41's back in the 1970's. Although I had very little helm time on the 41, my sense was that these boats went to weather and close reached extremely well, expecially for that era. Where they got squirely was broad reaching and running, which was a product of the hull shape and rig proportions rather than a keel or rudder issue.
