you could use a nice stainless steel anchor chute robust enough for the loads that can be applied without having to add the standard fiberglass pulpit and steel anchor chute. You would probably have to have this made. The flimsy stuff I see available is not worth putting on your boat. I have seen too many of them mangled up. The anchor chute on a Hatteras is made with 316 stainless and is about 3/8ths inch thick with a stainless steel roller, instead of the flimsy rubber rollers you see on blow boats. I made my own from Hatteras drawings. If you can't find anywhere to get this done, let me know and I may be able to help you out. I would also recommend a real heavy duty windlass, you have to be careful with this because I personally think most of the recommendations based upon size ranges from the manufacturers do not recommend a large enough windlass for reality. Also, if you go with a 24 volt winch you can use smaller gauge feeder wire than if you use a 12 volt one. There are some horizontal winches that mount above deck so you won't have to make a large hole throught the deck, but you will have to make mount bolt holes and reinforce the deck from underneath. I have a Concept 2 windlass, you could probably use a Concept 1 with gypsy/drum combo or similiar rated windlass. The Galleymaid winches that Hatteras uses are monsters and expensive. There are several good winches for your size boat, just don't go too small, you will regret it. I would also recommend you add another 40 feet of chain to your setup.
