Frequently Asked Questions
What is a sounding lead used for?
A sounding lead is used to measure the depth of water under a ship's hull and to determine the vessel's draft during loading, unloading, or ballast operations. It is also used to identify the type of seabed for anchorage safety.
How do I choose the right weight of sounding lead?
The choice of weight depends on the water depth and current conditions. Lighter leads (2.5–5 kg) are suitable for shallow water and moderate currents, while heavier leads (7–10 kg) are recommended for deeper water or strong tidal flows. Always consult your ship's operational requirements.
Does the sounding lead come with a line?
The sounding lead itself is supplied without a line to allow you to use your preferred rope/wire. You can attach a marked lead line to the eye of the lead for depth reading. Marked lines are available as a separate item.
Is the sounding lead corrosion resistant?
Yes, the lead is made from high-density lead alloy, which naturally resists seawater corrosion. The integrated eye and markings are designed to remain legible in marine environments.
