marcosailfish,
I have a large carabiner clip attached to the ring on my anchor trolley. I keep my anchor line on a cuban yoyo hand reel and when anchoring I drop the anchor place the line within the clip and then trolley fore or aft as releasing scope of line. Once sufficient scope is out I set the anchor and tie off the anchor line to the cleat in front of the seat. Retrieving is the reverse taking in the scope wrapping around the yoyo reel till anchor is free and once along side the kayak I release the line from the carabiner clip and secure the anchor to the reel with a bungee and stow.
I installed my trolley with the ring at the bottom.
