The older 41, or more accurately the 410, is a totally different boat. The new 41 was designed by Glenn Henderson, and is a quicker boat, but slightly smaller in volume and length. We can keep full canvas up until 15-18 knots, and then reef our rolling furling main first, where the top of the main is equal in height to the head of the jib. We can sail that way until about 23-25 knots, and then reef both sails further. Of course, all this depends on your point of sail. These notes are for more close hauled sailing. When it's blowing on our nose over 25, we'll motor sail more often. We sailed up the Chesapeake last summer with a reefed main and full jib on a beam reach and the wind was about 22-25, and did a steady 7.5+ knots. Keep the boat on it's feet and it will fly.
