Someone referenced Beneteau parts system on this issue a couple of months ago. If I recall correctly Beneteau will set you up with all the necessary parts for a very resonable price. I also have a 361 w/o a windlass due to miscommunication with the broker. I opted to go with a Fortress FX16 rather than install a windlass. The anchor is lite weight aluminum and is fairly easy to retrieve once you break it loose. Good luck.
