I would agree with Pat--perhaps with one minor exception--or two. The windlass, chain and rode yes. I have the Delta 14, which is what most of us have on the 22 C Dory. I think you are going to have to find a real bargin to get the 22# at that price Pat mentions (they mostly run over $200)--and you may need to modify or replace the bow roller. I would buy a Ronca or Manson Supreme 15# over the Delta Fastset--and have used both the 22# Delta and the 25# Manson Supreme in testing in sand, mud, mud/shell conditons. I used the Manson for 3 years on the C Dory 25, including all of the PNW, from San Juans to the Broughtons, and a month in Alaska, plus several trips to Powell. I may buy a Ronca or Manson Supreme for my 22' C Dory to replace the 14.
The reason I would buy the Manson is that I have had a 14# Delta drag several times at Lake Powell. When that happened each time a 7 # Fortress (one of my two stern anchors--and now I have 3 Fortress/guardian aboard), set and held. There are some places, where the Delta will not penetrate the sand at Powell and will drag. I am sure that there are other places where this is true also. I have not had a Delta drag in the PNW.
The Manson is more expensive, but not much more so. You will have to modify the bow roller bale (assuming the boat has a roller bale) to fit the Manson or the Delta--although my Delta wedges into the bale, and I am satisfied with that--a larger roller would be better...The Manson (or Ronca)
are a different type of fluke which can come close to the boat--and if that is the case--then you may want to modify the roller. You can also have any good machine shop make a larger bale should not be expensive.
Congratulations on buying a C Dory 22. I assume you got the one we discussed.
Installing the windlass requires a 3" diameter hole saw, a good power drill capable of turning the 3" hole saw, with a 3/8" bit. When you cut the holes in the deck, you will want to under cut them with a dremel tool, or bent coat hanger on a drill, and remove about 1/8 to 3/16" of the balsa core-then coat the raw balsa with wet epoxy and fill with thickened epoxy, then smooth the center of the 3" hole--redrill with the 3/8. Using West Systems Six 10 thickened epoxy is an easier way to do this--and you may want to buy a tube of this for other epoxy potting projects on the boat. I like to make a backing plate for the windlass--or at the very least put in the largest 3/8 fender washers you can find. I have made the backing plate out of plywood or out of aluminum. This distributes the load over the deck much better. Use the same pattern for holes in the back up plate as you use for the deck.
Having said all of that, I still don't have a windlass on the current 22, and we seem to get by well--but I have a good strong wife to help! (in seriousness, we haven't been anchoring in deep water, and pop the anchor out with the boat. You should not pull the boat to the anchor, or break out the anchor with the windlass. You also should always take the rode off the windlass and put it on the cleat when you anchor. We have made covers for the windlass, which helps to keep any moisture out of the boat in heavy conditions. WE also put a keeper on the anchor when underway, not depending on the windlass to hold the chain.
