http://www.cabelas.com/cabelas/en/templ ... &noImage=0The deminsions are not listed from Cabellas but I can tell you the size I have is tiny. Probably 12-14 inches across and a little longer. Like I said the anchor hold on the 224 is meant for a fluke style anchor to be held across the opening and this one is actually to small to fit. It is easily the smallest anchor I've seen without going to one of those little mushrooms.
As far as size, from what I can tell the sundowner is 24 feet long and weighs about 4100 pounds. The smallest of these anchors is advertised for boats up to 25 feet. My 224 is 24' long and weighs 4400 pounds and it worked great. If you have a doubt spend the $5 extra and get the next larger size, I think you will still have more than enough room in your locker.
Also it says you don't need a chain due to it's design so I tried this and it held great. Don't get me wrong it doesn't hit the bottom and just stick but it worked really fast and I've never had an anchor catch immediately.
