Hi Alan
I will try and add some hints to help, but the best idea may be to offer to take you out or to come onbosrd with you to try and offer advice.
I also have both systems, and in nearly all fishing use the heavier anchor chain and alderney ring.
The stowage for my main rope is a cockpit locker, the Buoy is attached to teh ring and the anchor warp passed through prior to attaching the chain and anchor.
when in position the anchor is lowered from the cockpit, after it hits the bottom the warp is taken fwd while still paying out and under no load, it comes on deck via a fairlead, around the stem post and fwd over the bow roller.
As we drift back and are in position the warp is tied off on the spring cleat.
When lifting I take the tension off the warp with the engine and release the warp from the bow and motor around the buoy with the warp attached to the spring cleat. Then motor off untill the anchor is up in the alderney ring
Its then just a case of motoring the boat uptide of the buoy and pulling in a fairly light loaded warp.
I am fortunate enough to have picked a big bow roller that can be used in this way without removing the bruce anchor on the windlas system. When I first launched I strted by removing the bruce which I have now stopped doing as it is good to always have this rigged, and it means the other anchor can be stowed on our way in at the end of a day.
I hope that all amkes sense
as i said earlier its easier to show than discribe. Even with the boat alongside
My system is always dropped and recovered on teh stbd side, but that has never been a problem in 15 years using this technique on GW.
