There is a discussion about spinnaker poles in another thread at at this link where Michael Lusty found in the 2004 rules the requirement for a bridle was added. In 2005 when the class rules were updated to allow carbon poles, the bridal requirement disappeared. Bob Rutsch commented that he did not know if this was intentional, or an inadvertent omission when the rules updates were made.

Here are the applicable paragraphs from the 2004 and 2005 rules:

2004 Rules
5.11 Spinnaker Pole
.1 Material shall be of aluminum alloy extrusion and supplied only through a builder approved by the J/30 Class Association.
.2 Length from tip to tip of the pole shall not exceed 3810 mm nor when attached to the fitting at the mast, extend more than 3842 mm from the face of the mast.
.3 Bridle is required and the material is not restricted.
.4 Spinnaker pole end fittings can be of composite material such as the Forespar "ultra" series. A trigger mechanisms for holding the jaws open is not permitted.

2005 Rules & as currently worded in 2009 Rules
5.11 Spinnaker Pole
.1 Material shall be of either aluminum alloy extrusion or carbon fiber. The diameter of the an aluminum spinnaker pole shall not be less than 2 7/8 inches and a carbon fiber spinnaker pole shall have a uniform diameter through out of not be less than 2 1/2 inches.
.2 Length from tip to tip of the pole shall not exceed 3810 mm nor when attached to the fitting at the mast, extend more than 3842 mm from the face of the mast.
.3 Spinnaker pole end fittings can be of composite material such as the Forespar "ultra" series. A trigger mechanisms for holding the jaws open is not permitted.

Would the class measurer please investigate this and report back here? If it was removed intentionally, then the case is closed. If it was inadvertently dropped during the 2005 rules update, we should restore the rule as intended during the next time the rules are updated.
