In the compartment for the chain on the bow, there is always a certain amount of water. It's not small, about 5 cm. Water drain holes are located above the bottom and water cannot leak out. So one part of the chain is in the water practically all the time.
Do you also have water drain holes above the bottom of the compartment?
The chain started to rust, even though it seems more to me the part that is closer to the anchor, is the cause of this standing in the water?
What can I do?
