Rig a second rode. Lead it outside of your lifelines back to the cockpit. Then you can deploy an anchor from the cockpit at least as quickly as you can from the bow. Probably quicker, in fact, since you don't have to go forward.
I respectfully disagree with that.
First of all, it will be a terrible eyesore. Second, you will have that chain bouncing around the outside of your boat scratching the crap out of your hull. Lastly, if run on the outside, it would be a hazard when docking, possibly getting caught on a cleat or piling.
If you run it down the catwalk, then it is a tripping hazard. Nothing worse than rolling your ankle on a line or chain.
There was a time (before I marked my chain) that I followed some books advice about pulling my chain down the deck to measure it for scope. Seemed logical. I now find that advice poor seamanship. In a rocky anchorage (happens more than not), all you need to do is step on that chain or line and you have twisted your foot. Plus, the rhode inevitably can get caught on something as it plays out. This is one of those things I learned from experience. SO the thought of having 45 feet of rhode dangling off the side of my boat or on my catwalk while cruising (or even pleasure boating) scares me to death. Not with my crew (two kids).
There is a reason anchors and ground tackle are where they are on sail boats (free from running gear and stowed). Our running rigging always seems to be a magnet for anything that sticks up. I use these lights along the side of my lifelines (pictured below) and if I forget to take them off, they inevitably are ripped out by a sheet or tack/jibe. I have lost many lights that way. I cannot imagine having an entire anchor sitting up there waiting to grab it. In that case, I would actually be more scared the anchor would win!
Mantus has a VERY good product on their anchors. I like the idea and its ability to stow. I think this product is a good product too... but probably better suited for motor boats that do not share out running rigging issue. The exception here is if you purchase a backup anchor you wish to stow in the 'cockpit' area. As long as it does not have any chain/rhode attached to it, that would also work. But as a sailor, I would be really hesitant about putting that on my bow or anywhere forward of midships.
