Everybody is saying it, the new rudder, will change the boats performance, and that is the problem. When one buys a "one design" boat, you do not expect to have to spend money, above that for normal maintence and wear and tear, to keep the boat competitive. As far as being in irons, it is not that hard to get out of irons with a Sunfish. If being in irons is enough to make someone quit sailing, then I think that person is not willing to learn how to sail. ( I admit, today it seems like a lot of people want instant success, constant action with little work.) Perhaps they should get a PWC.
