The wing keel is being prototyped to try to improve
windward pointing ability and
not having to replace the
centerboard on my 1970 Irwin 23. The restoration project of this certified antique vessel is documented on http://www.angelfire.com/fl4/mft and a link is added to the
extensive list of projects completed and planned. The
Irwin 23 draws 2' 5" with the board up, 5' 9" with the board down. If the wing keel can
approximate the advantages of
the centerboard without suffering the deep draft of the
centerboard, this project will be a great success.
