The J30 doesnt have the retractable bow sprit for flying the asymetrical.
You get my hopes up and then crush them. You Bastard!!! (Sorry, I''m enamored of the modern flush bow, retracting bowsprit J''s I admit it, a fine asthetic that shows off a boats ability to perform (without being compromised to become a rules whore) just sends shivers down my spine)
And yet, she still has an air of... something fun to sail. I will have to con a ride on one of those shortly.
And now to go check out the rest of the boats you recomended. That name just caught my eye, and so I had to check on her first.
