I think the "Horror" stories generate from a previously owned boat that was NOT well maintained, Including Chick's.
Bene505, Brad also has some stories to tell.
But, if you keep up with it, it should not be an issue.
Finding a boat that is neglected should be the deal breaker. If the keel has been ignored than yes I understand that.
And those that have iron keels should maintain them just like any other system. If you don't, your resale value is going to take a big hit.
And BTW, I have about 10,000 photos of a 361 if you want to see them.
