Bob,
I just may be interested in the anchor. The one's I have are all to small they are rated for my boats size but just does not do it. The boat is on the heavier size and I was going to replace them in the spring but This one sounds like it will work.
I have a 22ft dry weight is around 4000 with fuel and crew I push 5500 to 6000 do you think it will hold? If so Give me a call or drop me an email if you do not have my number any longer.
