Do you know your windlass' pull force limit? (WPFL) Every
boat using chain, should know her
anchor depth limit:
Anchor Weight + Chain Weight/m X
Depth < WPFL
When you disregard the inequation by
anchoring in deeper waters you probably need to help your
windlass with your muscles.
The anchor weight is a constant value. But the chain load to
windlass is varying according to the length of the chain droped in to the
water. So keep in mind that chain size is important when you think about the max. depth you can anchor.
