On Wednesday nights, the J/80 class isn't in One Design mode, so certain sailors would lobby NOT to have a dedicated class.
There are currently 3 J/80 PHRF ratings: 126, 129, 132. Rating 129 is the most common, however the sail sizes for boats sailing with 129 are not consistent.
There has been discussion about movement toward a one design mode. We are at least a year away. Maybe 2024 we'll have a OD class on Wednesday nights.
