I also had that problem with the anchor striking the roller furler drum during stowing. I solved it by installing another pin through the roller housing to hold the anchor down as it passes the drum. Works fine.Have Mantus 45# anchor on my 41DS. Works great. Only small issue is top of shank hits bottom of roller furler when raising anchor to stored position in bow roller.
