So I am in the hunt for my first sailboat. Looking in the 22 - 27' range. I am looking at Seafarer, O Day, Morgan, Kells, Catelina, Lugar and even found a cool Grampian (so ugly she's pretty!

). What are the pros and cons to the swing keel? I know obviously that having the swing keel will allow me to enter more shallow waters. I will be in the LI Sound and Easter Seaboard so shallow waters are very few and far between.
Thanks!!
