Connecticut Safe Boating Practice Test

What is the recommended length of the anchor line?

1. 3-5 times the maximum water depth

2. 5-7 times the maximum water depth

3. 7-10 times the maximum water depth

4. 10-12 times the maximum water depth

The correct answer is: 7-10 times the maximum water depth

The recommended length of the anchor line being seven to ten times the maximum water depth is based on principles of effective anchoring and ensuring a secure hold. This ratio allows for an optimal scope — the angle at which the anchor begins to hold. Using this length not only ensures that the anchor can set itself properly into the seabed but also allows for changes in water conditions, such as tides or waves. This gives the vessel better stability, reducing the risk of dragging the anchor in windy or turbulent water. This practice maximizes the holding power of the anchor and enhances the overall safety of the vessel while at anchor. In contrast, shorter anchor lines may not provide enough scope for proper anchoring, while excessively long lines could lead to tangles or difficulties in retrieval, thus making the anchor less effective. Thus, maintaining a length of seven to ten times the maximum water depth helps in achieving an effective and safe anchoring situation.
