About the J105 PDF Print E-mail

Introduced in 1992 as the first modern day keelboat with bow sprit and asymmetric spinnaker, J/105 today is the most successful one-design keelboat class over 30' in the USA with over 670 boats sailing worldwide.  The class association is an owner managed organization with strict one-design rules, a world class web site, and offers the best and most active one-design racing in the USA today. The class rules include an owner-driver rule, tight restrictions on Category 3 professionals (read none), and annual sail purchase restrictions to keep racing affordable and as Corinthian as modern one-design can be.  In Europe, J/105 has proven to be the double handed boat of choice for offshore sailors and recently won the RORC Yacht of the Year and scored notable double-handed wins in the 2007 Rolex Fastnet Race and the 2007 Rolex Middle Sea Race etc...  Owners rave about how well the boat sails in even the most extreme of conditions.
