Local conditions at our new home port make the recommended anchor for our 30 foot, 10,500 pound Hunter a Bruce 22 pound with lots of chain. There's not enough room in the locker for this load and We'd like to carry the anchor on a good bow roller. The products I've found are Windline Marine's BRM-3 and BRM-4. Can anyone share their experience changing out the factory bow roller to one that accomodates the Bruce? (removing the old and fastening the new)
