Tactical anchoring sounds like a good idea in theory but in practice I see some real problems.
1. The helms person will not be able to see the bowman (visibility is that bad)
2. Even if they can see the bowman how do you communicate. It is impossible. How do you anchor with no communication.
3. Being on the bow is just a bad idea. A very strong person would need both hands just to hang on. How is he going to handle an anchor?
4. Assuming all of those obstacles are overcome the chance of the boat drifting in an unexpected direction and fouling the prop and or rudder or keel approaches 100% in my opinion.
5. Assuming the above is survived and the anchor is in the water and the rode is payed out the trivial act of securing the line on chocks has the significant risk of removing fingers.
In short it would be a very different set of circumstances that would cause me to use the anchor during a big storm. If I could get it down before it hit maybe?
