As I do 100% anchoring without a crew I do have a little experience in this matter.
1st thing I did with my past and present yachts was removing the admiralty anchors, happily now sitting in garden beds on dry land where they belong!
2nd I modified the roller systems to pivot and take a suitable anchor. The Marsh is best as it has a round shank which helps with retrieval as it can sit anyway it pleases when it hits the rollers.
3rd is to have a up/down switch in the cockpit.
When deploying the Anchor I hold the boat into the wind and dump chain with the switch only using reverse if I feel the chain is piling up on the seabed
which usually happens in a no wind situation. in a good breeze it is easy to keep her into the wind laying out the chain using a combination of reverse and forward and on and off with the chain dump.
It is important that you don't allow the boat to sail sideways during this practice as I witnesses a catalina 42 yesterday and another yacht a few weeks ago both with admrialtys and both dragged before the anchor had set due to increasing water depth and dragging the anchor out of the sand and into weed.
Retriveal is much the same , in light winds I let the winch do the work dragging me slowelly forward using the up switch on/off in intervals not to overload the circut breaker and gear. If it is breezy I will use a bit of both engine forward and anchor up Always trying to keep the bow into wind till the last meter of chain.
Finally I try always to anchor in no more than 10 meters of water and in sand if possible. Polarise Sunglasses are a must for such activitys.
hope this helps.
