I have found that the rode-only anchor windlass that came with my Cat320 is practically useless. I can easily motor up to the anchor and bring in the rode by hand. It's the chain and anchor that is the back problem. A friend with a new Cat 310 has the same issue. Has anyone retro fitted a chain hub or tried a diferent windlass ? I am hoping to find something that will fit into the anchor well and replace the present one, without modifying, if possible.
