Ballast is used in sailboats to provide moment to resist the lateral forces on the sail.
Ballast is used in sailboats to provide moment to resist the lateral forces on the sail.
As we know, on larger modern vessels, the keel is made of or filled with a high density material, such as lead. However, lead is not environmental-friendly, so owning to high density and non-toxic, tungsten heavy alloy is increasingly adopted in tungsten alloy counterweighs for sailboat. By placing the tungsten alloy counterweight as low as possible (often in a large bulb at the bottom of the keel) the maximum righting moment can be extracted from the given mass. Traditional forms of ballast carried inside the hull were stones or sand.
Special Properties for Tungsten Alloy Weights of Ballast System
Here are some main advantages of tungsten alloy counterweight:
– High density up to 18.5 g/cm3.
– Up to 65% denser than Lead.
– Up to 130% denser than Steel.
– Mechanical properties to suit either dynamic or static locations.
– Weakly Ferro magnetic.
– Non-magnetic, if specifically required.
– Alternative to Lead.
– Non-Toxic.
– Corrosion resistant.
– Easily machined.
– Easily mechanically joined, brazed or shrunk fit to other materials.
– Equivalents to most commercial specifications available.
