In my case, my boat is old and had been cared for poorly. In my effort to refurbish her some things happened that I expect would make it too hard to bring her back to OD spec. For example, my cockpit lockers are gone; had to go to repair the deck under the winches. Some other significant things changed down below as I determined that various items were unrecoverable. My new primaries aren't on your list either, though I believe mine are heavier (and considerably less expensive self tailers). Anyway, I don't expect any serious J30 OD competition on my puddle. Enjoy it if you can get it.
