The 28 is a Perry design. Never sailed one. The 30 is a Bob Finch design. The 30 is less money out lay, but needs a bit of tidying up. I do not like the lose wires at the radios. Little thing like that. The 28 needs some electronics for navigation. Think I could get by with out them, but sure would make life easier. The Irwin, I could sail away tomorrow. I wish I had a little fairy godmother to make the decision for me. Then, if something went wrong, I could blame her.
