I've seen some people with the type of pulpit you have carry a Danforth partially deployed. So the shank is up in the air at an angle with the flukes below the pulpit and the anchor is kept from deploying any farther by a chain hook and a hold-back line. But even in this position the cross-bar (I forget the correct name) of the Danforth could foul the plow anchor next to it.
I have also seen brackets that hold a Danforth-type anchor vertically on a bow or stern rail. The aesthetics of this will depend on the configuration of your boat and what you think looks okay, but the relatively flat Danforth works well in this vertical stowage position.
I can understand the advantage of having two types of anchors when a boater is faced with several types of bottoms, as is the case here in the PNW. It's not uncommon on larger boats with a side-by-side pulpit arrangement in this area to have a Bruce and a CQR, for example, or a Danforth and a Bruce. On a GB-type pulpit with the bow rollers at the end of the pulpit rather than set back as in the photo, a Danforth fits fine.
When faced with sand, mud, gravel, rock, weed, and ooze bottoms as we are here, some anchor types are good for some of them but not necessarily all of them. And some anchors (some of us believe) are good for all of them.
But if the bottoms one normally encounters are suitable for one type of anchor, I've never quite understood the idea of a "lunch hook" as well as a "primary" anchor. Assuming one has a windlass to haul it up, why not just use the one main anchor for everything, short stays as well as overnight or multiple day stays?
We carry a Fortress on the swim step as a stern anchor. It's rode is in a covered milk crate on the aft deck. The Fortress and its rode are sized to be the main anchor for our boat. So if we decide the Fortress would do a better job of holding in a particular situation than our main anchor, its light weight makes it easy to carry forward and deploy off the bow. This works well with our boat's configuration--- it may not be practical on a differently configured boat.
