On our first SE Alaska & Yukon trip in 2003 we had a 11# Lewmar Claw anchor. I found it difficult to get a good set & even then if bottom conditions not near perfect it would not hold well, so on our 2004 SE Alaska cruise from Prince Rupert, BC, switched to a 22 lb Lewmar Claw & used it on our 2007 SE Alaska cruise as well. It was somewhat difficult to get a good set, but once set held very well, except in soft mud. In the soft mud it would just scoop up the mud in the flukes then skate on the mud surface with almost zero holding resistance. With that experience, I switch to a Manson Supreme 15# & then with a added windless to a 25# Manson Boss. I tried the Manson Boss in the same Alaska location where the Lewmar Claw wouldn’t hold & it instantly set & held there as well as every other place tried except for a rocky kelp covered bottom that wouldn’t have been good for holding with any anchor that would fit the pulpit of a CD22. My experience has shown me the newer style anchors like the Manson, Mantus, Ronca & Vulcan are all better then the claw. I now carry the 15# Manson Supreme as a spare. No doubt there are bottoms, where a totally different type anchor would be the best choice for a spare, but I haven’t found yet a need for any other then the Manson with others like the Ronca or Vulcan just as good. I do also have a Dansforth fortress, which I used in the past as a spare & for a lunch hook, this was back when I was using the 22# Lewmar Claw with 30 feet of chain & didn’t have a windless. At the present I think, the 15# Manson Surpreme is my best choice as a spare.
Yes, like Bob said the smaller anchors of the type he mentioned will hold if your are experienced & get a good set, but for most, I believe a heavier anchor up to 25 lbs & 50 feet of chain on a CD22 is a better choice depending on your area & type of cruising planned. The heavier anchor & chain will require the use of a windless.
