Healy's ideas on the J/24 could be applied to the J/30. No surprise since they were designed by Rod J just two years apart. I'd be in favor of lowering the weight limit now 7 x 200=1400 lbs to 6 x 180=1080 lbs. By comparison the 34 foot, 8575 lbs J/105 is longer and heavier than the J/30, but has a crew weight limit of 1045 lbs.
As indicated in the article, that would mean using the Genoa only up to about 12-14 knots. Although I am unconvinced that an aramid mainsail would be more durable, if you eliminate the Genoa, add a backstay flicker, and increase the mainsail roach supported by a full length batten, it might make sense.
The boat would be easier to staff and sail, safer since the skipper could see to leeward, but like the J/105 slow death upwind on those light air days typical of the Chesapeake and LI Sound.
