Common usage would have you believe that all keels need a keel weight, but many catamarans have sharper structures on the bottom of their hulls that are called keels. Generally a keel is not retractable, a centreboard is.
- nicwolff 10y agoThough we do use the term "swing keel" for a large heavy centerboard.
- escape_goat 10y agoAre these functionally distinct from normal centreboards? I'm trying to recall the term and what comes to mind is a keel that's hung like a centreboard to reduce grounding damage.
- wtallis 10y agoThe Catalina 22 is available with a swing keel that is about 550 lbs. Those models have no other keel. By contrast, my Morgan 24 has a full-length shallow keel with 1900 lbs of ballast, plus a fully retractable centerboard that is not particularly heavy. I think the only common distinction between the terms "swing keel" and centerboard is whether it provides appreciable ballast.
