A recent rule change effective 1 January 2016 added the following paragraph under 4.3 The following are permitted while racing:
4.3.16 A Bob Stay using high –modulus polyethylene fiber (e.g., Dyneema™ or Spectra™) secured in the bow above the waterline and on the Bow Sprit, provided that a Bob Stay may not be used while racing under J/109 one design rules unless specifically permitted by the sailing instructions for the event, or the local Fleet Captain has issued instructions that Bob Stays are allowed for events sanctioned by the local Fleet. Local Fleet Captain instructions do not apply to Class sanctioned events.
This notice is to inform those who race in any event scheduled in the Fleet #6 area, that Bob Stays will be allowed for all events, unless that event has been declared as "Class sanctioned event". The 2016 J/109 North American Championship scheduled at New York YC Race Week is an example of a Class sanctioned event where Bob Stays will not be allowed.
If you have any questions, please let me know.
Happy Holidays and best wishes for a wonderful New Year!
