I have a 30' cabin cruiser and was using a danforth style for a while (fortress). It held great as long as I had the right scope. This usually meant I had to get in the water to both set and retrieve it. As someone who boats from May to Oct, I was looking for an alternative to that requirement and found a great one.
It's called a box anchor. I got the large size for the stern and I can throw it off and it sets immediately (except in grass and weeds, but I avoid those areas). It doesn't require the same scope as the danforth. And the best part is it folds up nice and flat. I also got a Danik hook which makes connecting and adjusting the length very easy.
