Jim, I think you're asking the wrong question...
If you row away from your boat a bit, and then sit and look at her while she's snugged in, it will be a 'system' you are looking at, not an anchor. I think you want to reflect on what 'system' best meets your needs.The Bay: as accurately described earlier, it's mostly mud but with some hard pan (e.g. Inner Harbor but also in the bends of some tributaries with good tidal flow) and some shell, some but less grass than we'd all like (more would be a healthy sign) and also clay. The wx is normally benign but seeing 60 kts in a T/S is just about everyone's experience one or more times each season if you anchor out much. So...multiple bottom types and the rare but not unexpected gale/storm force wind.The Boat: Lots of freeboard & windage, not a lot of boat under the water, relatively light and with a tendency to sheer about on the hook, perhaps offset by stuff back aft. Relatively thin gauge anchor platform(s), perhaps cantilevered too far off the bow and with hard edges that can chafe nylon quickly.Rode: Consider adding enough chain to avoid chafe on the shell bottom and to settle her down in the frontal patterns & T/S's. (Personally, given the nature of the boat, I'd recommend H/T chain and keep the weight off while maintaining high WLL). Use shackles rated for your chain (they rarely are). If you go with enough chain that not all of it will be deployed in some anchorages, have several 20-25' snubber lines to hand and learn how to tie a rolling hitch (chain hooks fall off; plates are hard to attach when you're trying to do two things at once).Anchor: Given all the above and the investment in your nice boat, I can't imagine not carrying one large fluked and one burying anchor - Danforth/Fortress, CQR/Delta/Bruce - and being set up to handle two rodes via a windlass.Perhaps the new Hunters are differently equipped than what I've seen twice at boat shows this year, but I really urge you to look carefully at that anchor roller/platform if it's what I've been seeing. This arrangement isn't Hunter's alone (look at the Catalinas...) and, especially with the bigger boats like yours, a heavy wind and a sheering load on a thin-gauge, cantilevered platform is going to end up making you unhappy. I've seen some clever replacement/upgrade ideas posted by some of the Catalina owners.Good luck on a great upcoming season. Friends on the Bay are already sending me gloating emails about how the wx has turned down there!Jack
