You must be an owner of a J30, sailed in to J30 regattas, and be a member of the J30 Class
for 60 days prior to the event. See below for the exact wording:
6.6 Helmsman Rule
.1 Any helmsman racing in a one-design Class event shall be an owner of the yacht he is helming. The owner or owners shall helm the yacht from the warning signal until the finish except for momentary absence due to personal, safety, or shipboard needs.
.2 In one-design Class distance races designated by the local fleet, the owner or owners shall helm from the warning signal and for the first hour, for at least one-third of each leg, during all mark roundings, and for approximately the last hour of the race until finished.
.3 An owner is any person who legally owns 100% of the yacht or is at least a twenty-five percent partner in terms of financial investment in the purchase of the complete yacht and the cost of its operations. Ownership shall include long-term charter arrangements of three months or more at fair market value.
.5 Ownership is automatically conferred on the members of the owner's immediate family including children, parents, and spouse.
.6 To be eligible for national championship events, the owner must have been a J/30 Class
Association member for at least sixty days prior to the event, helmed the yacht in at least two regattas in the preceding sixty days and satisfied any and all District qualifying requirements. The Class President shall determine eligibility for national events and may alter or waive qualifying requirements in special circumstances.
.7 Owners are eligible to helm another J/30 as if it were their own yacht, if it is loaned or chartered in either an event outside that owner's home waters, or in any case where the owner's own yacht has been damaged and is not capable of being sailed.
.8 Local fleets may waive or modify the Helmsman rule for local events only.
